James McStay (1 April 1895 – 31 December 1973) was a Scottish football player and manager.
The siblings played together 246 times for Celtic[3] as well in as one Scottish League XI match in 1926[4] and a Scottish Football Association summer tour of North America in 1927;[5][6] however unlike Willie, Jimmy never gained a full international cap.
Taking all cups into account he played in exactly 500 matches for Celtic,[7] ranking 14th on the club's all-time list and making the most appearances overall for the Hoops without being selected for his country (Charlie Shaw holds the unwanted record in terms of Scottish Football League matches).
[8] He also managed Irish club Brideville and Alloa Athletic prior to his appointment at Celtic,[9] and afterwards took charge of Hamilton Academical[10] (where he had also finished his playing career, appearing for Accies in the 1935 Scottish Cup Final aged 40).
[11] In addition to Willie and Jimmy, another McStay brother, Francis, was also a footballer, played for Motherwell in the 1910s.
