The discography of Irish singer-songwriter Enya consists of eight studio albums, two compilation albums, twenty-one singles as lead artist and a number of other appearances. Enya achieved a breakthrough in her career in 1988 with the album Watermark, containing the big hit song "Orinoco Flow" which topped the UK Singles Chart and the European Hot 100 Singles. Three years later, the similarly successful Shepherd Moons followed, which debuted at the top of the charts in the United Kingdom and featured the moderately successful singles "Caribbean Blue" and "Book of Days", the latter was the theme of the film Far and Away. In 1992, a re-mastered version of the 1987 Enya album was released as The Celts with the title track as a single.

Four years after Shepherd Moons, she released The Memory of Trees in 1995, a top five success in several countries around the world, as well as her first top ten album in the United States. Singles released from the album were "Anywhere Is" and "On My Way Home", the first was a top ten hit in the United Kingdom. In November 1997, Enya released her greatest hits collection, Paint the Sky with Stars: The Best of Enya. The compilation was a huge sales success, especially in the United States and Japan, and featured two new songs: the title track and the single "Only If...". The following month, the limited box set A Box of Dreams was additionally released, containing three discs and some B-sides from previous singles.

Following a five-year break, Enya released her most successful studio album to date, A Day Without Rain. The album peaking at number two on the US Billboard 200 albums chart and became the best selling new-age album in history. The first single, "Only Time", was used in the film Sweet November and reached the top ten in the United States and number one in Germany. The second single, "Wild Child", was included as the main theme of the soundtrack of the film Calmi Cuori Appassionati, which was Enya's second album to sell over a million copies in Japan. In 2001, Enya recorded the acclaimed song "May It Be", which featured in the first installment of The Lord of the Rings film series, The Fellowship of the Ring, and was her second consecutive single to enter the German charts at number one. The following year, she released her third box set titled Only Time: The Collection.

Enya was formally credited on two hit singles in 2004, "I Don't Wanna Know" and "You Should Really Know", which contains a sample of "Boadicea" previously used by the group Fugees in the song "Ready or Not". The following year, she released her sixth studio album Amarantine, another top ten success in several countries. The title track became her highest-charting single in France and "It's in the Rain" became her highest-charting single in Italy. The album also marks the first published use of Loxian, a fictional language created by Roma Ryan inspired by the fictional Elvish languages by author J. R. R. Tolkien that she had used for Enya's songs for The Lord of the Rings: The Fellowship of the Ring. In 2006, Enya released the Christmas-themed extended play Sounds of the Season: The Enya Holiday Collection exclusively in the United States in Target stores.
