Robert Liddle (11 April 1908 – 12 April 1972) was an English footballer who played in the Football League for Stoke City.
Being primarily a right flank player, Liddle established a good rapport with right back and long serving captain Bob McGrory and the two became good friends. When a young up and coming Stanley Matthews burst onto the scene and took Liddle's number 7 position, McGrory took offence. McGrory became manager in 1935 and Liddle remained out of position but he regained his place during World War II with Matthews spending most of his time away with the RAF and making guest appearances. He retired once the Football League resumed in 1946 after making 316 appearances scoring 64 goals. He was then appointed club trainer a position he kept until 1953. He then moved to Nottingham where he became a newsagent until his death in 1972.
