Gary Brown (born 1 November 1980) is a professional rugby union player.

Brown would go on to earn 43 caps in the competition, playing in the positions of fullback, center and wing, scoring 11 tries.

Brown then played in his first Heineken Cup game in the 9–25 win against Treviso in Italy in 2004.

It was the first of 4 caps, before he opened up his try tally with a brilliant touchdown against Bourgoin in Lansdowne Road.
