William John Moffatt (30 June 1897 – 17 October 1952) was a Scottish professional footballer who played as a wing half or full back in the Scottish League for Bo'ness and in the English Football League for Portsmouth and Brighton & Hove Albion.
Moffatt was born in Bellshill, Lanarkshire, in 1897.[1] He played junior football for Bellshill Athletic before joining Bo'ness of Division Two.[1] He captained the team to the quarter-finals of the 1922–23 Scottish Cup, in which they performed well in a 4–2 defeat to Division One club Motherwell despite being handicapped by an injury to Moffatt.[2]
In 1925, he signed for English Second Division club Portsmouth. He soon established himself in the team, and was ever-present in the 1926–27 season in which they were promoted to the First Division.[3] He took his appearance total to 138 before being released in 1930 to join Brighton & Hove Albion of the Third Division South. He was already 32 years old, and Albion used him as a standby player to cover at right back and wing half. In his first season, he contributed to a run of 16 league matches unbeaten that remained a club record until 2015.[4] After two seasons and 23 appearances, he left the Football League for non-league football in the Hampshire area.[5]
Moffatt died in Southsea, Hampshire, in 1952 at the age of 55.[6]
