Sir Allan Maclean, 6th Baronet of Morvern and Duart (1710 – 10 December 1783) was the 22nd Clan Chief of Clan Maclean from 1750 till his death in 1783. He was the 4th Laird of Brolas. He died without leaving a male heir to his title, so the title was bestowed on his closest living male relative, a fourth cousin, Sir Hector Maclean, 7th Baronet.
