Thomas Lindsay Buick CMG (13 May 1865 – 22 February 1938) was a Liberal Member of Parliament for Wairau, New Zealand, a journalist and a historian. He published under the name T. Lindsay Buick.

Born in Oamaru on 13 May 1865, Buick was the son of Margaret (née Petrie) and John Walter Buick.^[1][2] His parents had emigrated from England to Port Chalmers in 1860. Buick received his education at schools in Oamaru and moved to Blenheim in 1884 to work as a carpenter. Although he had no relation to Ireland or Catholicism, he joined the Irish National League "purely as a lover of liberty and justice", and in 1889 he embarked on a speaker tour. He was also active in the temperance movement.^[1]

Buick married Mary Fitzgerald on 8 January 1891 at Blenheim; they were to have no children.^[1]

Buick represented the Wairau electorate in the New Zealand House of Representatives from 1890 to 1896, when he was defeated.^[3][4] The 1896 general election was contested by Buick and Charles H. Mills, who received 2014 and 2072 votes, respectively. Mills thus succeeded Buick.^[5] He was a temperance advocate and supporter of Irish Home Rule.^[6]

From 1893 until 1894 he was the Liberal Party's junior whip.^[7]

Years later, in July 1904 he unsuccessfully contested Pahiatua by-election as the official Liberal candidate.^[1]

Buick wrote numerous works on the pre-European and early contact history New Zealand, and two books on music. His The Treaty of Waitangi: or, How New Zealand became a British Colony (1916) remained the only substantial work on the Treaty until the late 1980s.

Later, he was owner/publisher of the Dannevirke Advocate.^[8]

In the 1933 King's Birthday Honours, Buick was appointed a Companion of the Order of St Michael and St George (CMG), for public services.^[9] In 1935, he was awarded the King George V Silver Jubilee Medal.^[10]
