McGill's Bus Services is a bus operator based in west central Scotland, with its headquarters situated in Greenock, Inverclyde.
The present company was founded in July 2001, restoring the name of a previous operator that had existed between 1933 and 1997.
The company has grown from an initial fleet of thirty-three vehicles to operate a network of routes covering much of Inverclyde, East Renfrewshire, North Lanarkshire, Glasgow city and North Ayrshire.
A second depot in Barrhead was opened in 2008, and four independent operators were taken over by McGill's in the following three years.
McGill's now has several depots in Greenock, Barrhead, Coatbridge, Inchinnan and Johnstone. McGill's is the largest independent bus operator in Scotland.
