Major The Rt Hon. John Maynard Sinclair (4 August 1896 – 31 January 1953) was a unionist politician in Northern Ireland. Born in Belfast, in 1896, son of John Sinclair DL and Alice Montgomery, he was educated at the Royal Belfast Academical Institution, and in Switzerland. He served in the British Army during World War I. He was a director of the Eagle Star Insurance Company and Chairman of Vulcanite Ltd.

His first attempt to be elected to the Parliament of Northern Ireland was unsuccessful; he contested the Mourne division in 1933. He was elected to the House of Commons of Northern Ireland in 1938 for the division of Belfast Cromac. On 16 January 1941, he was appointed Parliamentary and Financial Secretary to the Minister of Finance (i.e. a junior minister). In May 1943, Sir Basil Brooke succeeded John Miller Andrews as Prime Minister of Northern Ireland; Maynard Sinclair was appointed Minister of Finance (de facto Deputy Prime Minister) in the Government of Northern Ireland on 6 May 1943 and was made a Privy Councillor (Northern Ireland).

Maynard Sinclair was one of 133 passengers drowned in the sinking of the ferry MV Princess Victoria on 31 January 1953, en route across the North Channel from Stranraer to Larne. He was survived by his wife, Marjorie Claridge.
