Robert Lionel Seddon was an English international rugby union forward who played club rugby for Broughton Rangers and Swinton and county rugby for Lancashire. Seddon was capped at international level for both England and the British Isles. Seddon played three matches for England in 1887, and in 1888 was one of only four capped players to represent Britain in the 1888 tour of New Zealand and Australia. Seddon was given the captaincy of the British team, but died in a boating accident halfway through the tour. Seddon and the British team were honoured in 2013 with induction into the IRB Hall of Fame.

Broughton Rangers were one of the twenty-one rugby clubs which met at the George Hotel, Huddersfield, in 1895 to form the Northern Rugby Football Union. They were originally based in Broughton, Salford, but in 1933 moved to Gorton, Manchester to play at the Belle Vue Stadium, and were renamed Belle Vue Rangers in 1946. The club folded in 1955.
