Robert Mell (26 June 1872 – 11 November 1941) was a British trade unionist and politician.
Although Mell's birthdate and place are not known with certainty, Raymond Brown tentatively identified him with a child born in 1872 in Kilpin Pike, to Thomas or Brown Mell and his wife Sarah Willooghby in the East Riding of Yorkshire.
In time he became an engine driver, but remained with the ASRS and its successor, the National Union of Railwaymen (NUR).
He was a founding member of the party in Hull, and in 1912 he stood for election to the city council in South Newington.
[1] At the 1918 United Kingdom general election, he stood in Kingston upon Hull South West, sponsored by the Independent Labour Party.
