Maclean baronets
There have been two baronetcies created for persons with the surname Maclean, one in the Baronetage of Nova Scotia and one in the Baronetage of the United Kingdom. Both creations are extant as of 2010.

The Maclean Baronetcy, of Morvaren (or Morvern) in the County of Argyll, was created in the Baronetage of Nova Scotia on 3 September 1631 for Lachlan Maclean, with remainder to his heirs male whatsoever. His great-grandson, the fifth Baronet, was raised to the Jacobite Peerage of Scotland as Lord Maclean on 17 December 1716. The line of the first Baronet failed on his death in circa 1751. The late Baronet was succeeded by his kinsman, the sixth Baronet. He was the great-grandson of Donald Maclean of Brolas. He was succeeded by his kinsman, the seventh Baronet. He was the grandson of Hector Og Maclean of Brolas, great-uncle of the sixth Baronet. He died unmarried and was succeeded by his half-brother, the eighth Baronet.

His great-great-grandson, the eleventh Baronet, served as Chief Scout of the Commonwealth, as Lord Lieutenant of Argyllshire and as Lord Chamberlain to Queen Elizabeth II. In 1971 he was created a life peer as Baron Maclean, of Duart and Morvern in the County of Argyll, in the Peerage of the United Kingdom. On his death in 1990 the life barony became extinct while he was succeeded in the baronetcy by his son, the twelfth and (as of 2010) present holder of the title. He is the 28th Chief of Clan Maclean of Duart. The ancestral seat of the Maclean baronets of Morvaren is Duart Castle on the Isle of Mull.

The Maclean Baronetcy, of Strachur and Glensluain in the County of Argyll, was created in the Baronetage of the United Kingdom on 22 July 1957 for the diplomat, soldier, writer and Conservative politician Fitzroy Maclean. As of 2010 the title is held by his son, the second Baronet, who succeeded in 1996.
