There have been three baronetcies created for persons with the surname Foulis, one in the Baronetage of England and two in the Baronetage of Nova Scotia.
The Foulis Baronetcy, of Ingleby in the County of York, was created in the Baronetage of England on 6 February 1620 for David Foulis. The third Baronet sat as Member of Parliament for Northallerton. The title became extinct on the death of the ninth Baronet in 1876.
The Foulis, later Liston-Foulis Baronetcy, of Colinton near Edinburgh, was created in the Baronetage of Nova Scotia on 7 June 1634 for Alexander Foulis, with remainder to heirs male whatsoever. The second Baronet was a Member of the Scottish Parliament for Midlothian and served as Lord Justice Clerk with the judicial title of Lord Colinton. The third Baronet sat in the last Scottish Parliament and then represented Midlothian in the British House of Commons. He was also a Lord of Session and member of the Scottish Privy Council. On the death of the sixth Baronet in 1825 the male line of the first Baronet and his father died out. The late Baronet was succeeded by his distant cousin, the seventh Baronet, a descendant of George Foulis, of Ravelstoun, uncle of the first Baronet (see also the 1661 creation below). The eighth Baronet married Henrietta, great-niece and testamentary heir of the noted diplomat Sir Robert Liston, and assumed the additional surname of Liston. The thirteenth Baronet discontinued the use of the surname of Liston in 1988 by decree of the Lord Lyon. The title became extinct on his death in 2006. The family surname is pronounced "Fowls".
