Alexander Kenneth Maclean, PC (October 18, 1869 – July 31, 1942) was a Canadian politician.
Born in Upper North Sydney, Cape Breton County, Nova Scotia, Maclean was educated at Pictou Academy and Dalhousie University. A lawyer, practising in Lunenburg, Nova Scotia, Maclean first ran unsuccessfully for the Canadian House of Commons in the 1900 federal election for the electoral district of Lunenburg. In 1901, he was elected to the Nova Scotia House of Assembly for Lunenburg. A Nova Scotia Liberal, he served until 1904 when he was elected to the House of Commons representing Lunenburg.
He resigned as an MP in 1909, when he was re-elected to the House of Assembly and was appointed Attorney General and Commissioner of Crown Lands in the cabinet of George Henry Murray. He served until 1911, when he was elected again to the House of Commons for the electoral district of Halifax. As a result of the Conscription Crisis of 1917 he crossed the floor on October 10, 1917 to support the Unionist government of Sir Robert Laird Borden and was a minister without portfolio in the Cabinet. He left the government in 1920 and was re-elected as a Liberal in the 1921 general election. He resigned his seat in 1923 and returned to private life.
