William James Abraham

William James Abraham (1883 – September 1927) was a British trade unionist and politician who served as president of the National Union of Railwaymen (NUR).

Born in Colmworth in Bedfordshire, Abraham became a railway signalman, based in Sheffield, and joined the Amalgamated Society of Railway Servants (ASRS). This became part of the NUR, and Abraham served as secretary of its Sheffield No.2 Branch for many years. This was an important branch, and by 1915 he was regarded as the most significant figure on the left wing of the union, leading arguments at its annual conference until the end of the decade. He also served as the president of the Sheffield Trades and Labour Council.

Shortly after the election, Abraham's health worsened, and he retired from his political and trade union activity to his family's dairy farm in Colmworth. He died there in September 1927.
