Horace Matthew Moulden-Colton (14 July 1898 – 30 April 1988) was a British trade union leader. Born in Leicester, Moulden left school at the age of thirteen before completing a short apprenticeship in hosiery knitting. He spent four years fighting in World War I, but returned to knitting and became active in the Leicester Hosiery Union. In 1921, he became a collector and workplace leader for the union, and two years later he was elected to its executive. He died at a nursing home in Leicester, a few months shy of his 90th birthday.
