Thomas Law (1 April 1908 – 17 February 1976) was a Scottish footballer. Playing at full-back, he spent his entire professional career at Chelsea. Born in Glasgow, he signed for David Calderhead's Chelsea from local junior club Bridgeton Waverley and made his English Football League debut in 1926 against Bradford City. He soon established himself as Chelsea's first choice full-back, a position he would hold for most of his time at Stamford Bridge and was one of the less glamorous, though more reliable, members of a star-studded Chelsea squad which included his Scottish teammates, Hughie Gallacher, Alex Jackson, Willie Ferguson and Andy Wilson. He made 318 appearances for Chelsea, scoring 19 goals, mainly from penalties.
