Alexander Lindsay, 2nd Earl of Crawford (c. 1387–1438/1439) was a Scottish magnate. He was the son of David Lindsay, 1st Earl of Crawford and Elizabeth Stewart, daughter of King Robert II and Euphemia de Ross. He was knighted at the coronation of King James I on 21 May 1424, and subsequently was one of the hostages for King James given over to the English from 1424 until November 1427.
He married Marjorie whose parentage is as yet unknown, although she is theorized by some to have been a daughter of the Earl of Dunbar, and had issue.
