South Yorkshire Transport (SYT) was a bus operator that provided services around South Yorkshire and outlying areas. The company was formed as an 'arms-length' successor of the South Yorkshire Passenger Transport Executive (SYPTE) in 1986, which was broken up as a result of the deregulation of bus services. South Yorkshire Transport operated buses in and around Doncaster, Rotherham and Sheffield with some services extending to Chesterfield, Leeds and Barnsley.
