Major Brinley Lewis (4 January 1891 – 2 April 1917), known as Bryn Lewis, was a Welsh international rugby union wing who played club rugby for Newport and Cambridge University.

He is one of twelve Welsh internationals to have died in active duty during World War I. Lewis was born in Pontardawe, Wales but was educated at Swansea Grammar School and represented the Wales Schoolboy team.

Lewis gained his first cap for Wales against Ireland as part of the 1912 Five Nations Championship.

The Welsh team was inexperienced and lost the game 12–5, not helped when Lewis's teammate Tom Williams broke his arm and continued playing in the second half of the game.

A scorer of one of the Irish tries in that game, Albert Stewart, would like Lewis, die in action in World War I. Wales[4] During the First World War, Lewis was a Major in 'B Battery' of the 122nd Brigade of the 38th (Welsh) Infantry Division, and was mentioned in Despatches.
