Allahabad was an iron-hulled full-rigged ship, built in Liverpool in 1864. She was later re-rigged as a barque and disappeared in 1886 on a voyage from Scotland to New Zealand.

Allahabad was launched on 19 September 1864 by W H Potter & Company in Liverpool, as an iron full-rigged ship of 1,185 registered tons.^[1] She had a length of 205.6 feet (62.7 m), a beam of 34.7 feet (10.6 m), and she had a 22.5-foot (6.9 m) depth.^[2] The ship was built for the shipowner James Baines & Co. of Liverpool and began her maiden voyage from there, to Calcutta, on 10 December 1864.^[3][4]

In 1877 she was re-rigged as a barque and re-measured as 1,191 tons gross and 1,143 net register tons.^[5] At the time of her loss she was the property of Thomas Wall Stephens of London and him being the managing owner.^[6]

Allahabad last left Glasgow on 2 July 1886, with a crew of 20 and a cargo of 1,712 tons, of which 1,635 was coal, bound to Dunedin, New Zealand. Having been signalled on 7 July off the Tuskar, she was on 4 September following, spoken, in about 29°S 28°W by the ship South Australian. From that time she has not been seen or heard of, and never arrived at her destination.^[7][8]
