Captain Herbert James Moss (22 February 1883 – 1956) was a British sailor, Army officer, and Scottish Unionist Party politician. He was the Member of Parliament (MP) for Rutherglen from 1931 to 1935.^[1]

Apprenticed to a ship as a boy, Moss received his master's certificate before the age of thirty. During the First World War, he was with the Royal Engineers and commander of a unit in East Africa. He then headed commercial houses in Glasgow and was a member of the Glasgow Corporation from 1927 to 1930.

After unsuccessfully contesting Glasgow Shettleston in 1929 and Rutherglen in the 1931 Rutherglen by-election, he was returned for Rutherglen later that year. In 1934, he, alongside William Paterson Templeton MP and a former Glasgow town councillor, were convicted of contravening to the Lotteries Act in connection to the Modern School of Art Union Cesarewitch draw. Moss was sentenced to a £50 fine or three months' imprisonment. Moss claimed that the breach was a technical one and vowed to clear his name. In January 1935, the Rutherglen Unionist Association passed a resolution calling on him to resign as MP.

He published his memoirs, Windjammer to Westminster, in 1941.
