Boardwalk Hall Auditorium Organ	United States	Boardwalk Hall Atlantic City, New Jersey	Midmer-Losh Organ Company, 1929-32	7 manuals 314 stops 449 ranks 33,451 pipes[5]	The largest pipe organ ever built, based on number of pipes. It weighs approximately 150 tons. Most of the organ has not functioned since 1944; a partial restoration in 1998 was largely reversed by construction damage during a renovation of the Boardwalk Hall shortly afterwards. Parts of the organ are again being restored to playing order in a $16M restoration effort that is expected to be completed by 2023. The Historic Organ Restoration Committee reports that as of 2018, 95% of the Ballroom Organ is operational, and 50% of the Main Auditorium organ is operational.[6] Restoration work is ongoing to the extent that public concerts have resumed.[7] It contains the world's largest Diaphone, the 64 ft Diaphone-Dulzian in the Pedal Right Division, which is also one of only two full-length 64 ft stops in the world, the other being the 64 ft Contra-Trombone stop at the Sydney Town Hall Grand Organ (See below)[8] The Grand Ophicleide (organ stop) in the Pedal Right Division, speaking on 100" wind pressure, is also recognised by The Guinness Book of World Records as the loudest organ stop in the world. It is described as having "a pure trumpet note of ear-splitting volume, more than six times the volume of the loudest locomotive whistle". In fact, the Grand Ophicleide produces 130 dB at 1 meter distance.[9]
Wanamaker Grand Court Organ	United States	Wanamaker's (Now Macy's Center City), Philadelphia, Pennsylvania	Los Angeles Art Organ Co., 1904 Wanamaker store Organ dept, 1914-17, 1924-30	6 manuals 376 stops 464 ranks 28,750 pipes	The largest pipe organ in the world, based on number of ranks and physical mass weight. It ranks second in the world based on number of pipes.[10] It is the largest fully operational musical instrument in the world, with the weight of 287 tons. This concert organ was initially constructed for the 1904 World's Fair in St. Louis; it was designed by George Ashdown Audsley. The organ was purchased by John Wanamaker for his palatial Philadelphia store; disassembled, the organ filled 13 rail cars. Uniquely, the Wanamaker Organ had from the beginning full-time organ fabricators and technicians, a true "organ shop", building it to luxurious standards of quality.[11] It is played twice a day, six days a week, and there are many recordings of this organ.[12] Its 88-rank String Organ is the largest division in any pipe organ in the largest single organ chamber. Its Pedal Organ of 75 ranks (supplemented by additional borrowed ranks) is the largest Pedal department of any instrument, possessing unsurpassed richness of tone with the capacity for subtle bass gradation in volume and complete separateness of musical line from the manual stops. At 71 ranks, its Swell Division is the largest Swell ever built. It is the largest organ built to a straight design with minimal resorting to unification. It has more expression pedals (10) than any other pipe organ, and 8 separately expressive pipe divisions. Despite its formidable size and power, its strength and hallmark is in musical subtlety and nuance. It is also recognized in the Guinness Book of World Records.

At the time of its installation it was the fourth largest organ in the world. The presence of the Wanamaker Organ ranked it as the second largest pipe organ in Philadelphia. For many years it was ranked as 11th largest by pipe count, but recent combining of instruments under single console control have placed it in the top 25 largest in the world by ranks or pipe count.

They are made from an alloy of highly polished tin. These pipes are arranged in a broadly curving arc, and lean outward at a four-degree angle, thereby coinciding with the architecture of the Hall's balconies. This is the first instrument ever constructed with pipes of this size mounted in this manner.[25]
Kotzschmar Memorial Organ	United States	Portland, Maine	Austin Organ Company, 1912	5 manuals 96 ranks 6,554 pipes[26]	This was the second-largest organ in the world when it was built, and is one of only two surviving "municipal organs" in the US.—the other being the Spreckels Organ in San Diego, California.

The golden decoration dates from the 16th century. In 1984 the pipes were reorganised into four cases (north and south), with two console.

Norway	Nidaros Cathedral	G.F. Steinmeyer & Company, Op. 1500, 1929-30 Kuhn Orgelbau, 2013-14	4 manuals[31] 129 stops[31] 201 ranks[citation needed] ~10,000 pipes[32]	Originally commissioned for the 900th anniversary of the Battle of Stiklestad. The organ was soon deemed too big for the cathedral, and as such moved and reduced in size several times through its history. It was in a sorry state for years before a full restoration brought it back to its former glory in 2014.[31] The casing and façade was completely rebuilt to seamlessly fit the western portion of the cathedral, and the organ got a brand new console incorporating modern digital technology. However, the new console has been modeled after the original 1930 console layout, and as many as possible of the old pipes were preserved. New pipes were only made where the original pipes had been lost.[33] In 2015 the new Choir Organ was linked together with the Steinmeyer Organ, giving the possibility of playing the combined 159 stops from the same console. However, despite these possibilities, the choir organ still retain its own console for independent use, and the cathedral administration promotes the two organs as independent and separate instruments.[34]

• The Bamboo Organ at St. Joseph's Roman Catholic Church in Las Piñas, Philippines, some 12 km from downtown Manila, is made almost entirely of bamboo. The building of the organ was begun in 1816 by the Spanish Augustinian Recollect, Fr. Diego Cera de la Virgen del Carmen, and completed in 1824. It has been damaged repeatedly over the years but always restored. After its restoration in 1975 by Johannes Klais (Bonn, Germany), a yearly International Bamboo Organ Festival has been held every year (second half of February). Recordings of the organ (by titular organist Armando Salarza, Guy Bovet, Hans and Martin Haselböck, L.Ferdinando Tagliavini exist and) are available online from www.bambooorgan.org
• The main exhibit in the Ontario Science Centre in Toronto, Ontario is a hydraulophone, a kind of water-jet organ. This pipe organ has hydraulic action provided by three water pumps and the keys on the organ console are water jets, so that each "key" (water jet) affords a richly intricate means way to independently control volume, pitch, and timbre affecting each of the organ pipes. See Opening and Lesson (how to play it).
• The 5/80 Wurlitzer Theatre Organ in the residence of Jasper and Marian Sanfilippo of Barrington, Illinois, USA is considered to be the finest example of extension organ in the world today. It is the 3rd largest theatre pipe organ in the world. The 2nd largest theatre pipe organ in the world is in Mesa Arizona at the Organ Stop and the largest theatre pipe organ in the world is the Carma Laboratories organ located in Franklin Wisconsin. ^{[49] [50]} The Sanfilippo organ was designed by David Junchen and installed in a purpose-built music room.
• The Organ of the Basilica of St. Martin (Weingarten), Weingarten, Württemberg, Germany, is built around six church windows, with a detached console facing the church. The tracker action is entirely mechanical, sometimes spanning as much as 20 metres, and going around several corners. It was built by Joseph Gabler during 1713 - 1750. Photos and details can be viewed here.

• Old Salem in Winston-Salem North Carolina has a Tannenberg Organ that was originally built in the 18th century. The case was built in Salem and the other parts were built in Lititz. Tannenberg was 72 at the time of the organ's construction, and was not able to make the trip to Salem to install it. The installation was done by George Currie of Philadelphia. Restoration of the organ has been made several times. One undertaking, in 1910, was not satisfactory, and in 2004 an extensive restoration was completed in Staunton, Va. It was then moved into the Visitor Center, where it is played by the Music Director of the museum. A tour of the bellows is available to visitors.
