Louie Ernest Brown (20 May 1905 – 3 June 1947) was a New Zealand professional rugby league footballer who played in the 1920s and 1930s.

He was joined in the senior side in the same season by his brother Roy (Ernest) Brown who played at fullback with Lou usually on the wing.

Brown played on the wing and scored a try in Wigan's 13–2 victory over Dewsbury in the 1928-29 Challenge Cup Final at Wembley Stadium, London on Saturday 4 May 1929.

[14] Brown played on the wing and scored a try in Wigan's 5–4 victory over Widnes in the 1928 Lancashire Cup Final during the 1928–29 season at Wilderspool Stadium, Warrington on Saturday 24 November 1928.

[16] In an obituary in the Gisborne Herald it was written that "one of the finest wing three-quarters New Zealand has produced, Lou Brown, has died in Auckland".

And that "Brown was rated as the finest wing three-quarter in England in 1929 when he scored a record tally of 43 tries in the season.

One of Lou Brown's most prized possessions was a medal which was presented to him by the French Rugby League commemorating his inclusion in the team"[18]
