Trent Ormond-Allen (born 11 June 1976) is a former professional Australian rules footballer who played for Melbourne and Adelaide in the AFL.
A top-ten pick in the 1993 draft, Ormond-Allen had to wait until the final round of 1995 to make his senior debut. After eight games for Melbourne, he was traded to Adelaide for a late draft pick at the end of the 1996 season. Ormond-Allen was a solid contributor in the Crows' premiership years of 1997 and 1998 but missed out on selection in the Grand Final both times. He played a total of 33 games in his first three years at Adelaide but, after failing to add to his games tally during the 2000 season, was delisted at the end of the year.
Ormond-Allen continued to play for Port Adelaide in the SANFL in 2001, before switching to South Adelaide the following year.
