Trent Ormond-Allen (born 11 June 1976) is a former Australian rules footballer who played with Melbourne and Adelaide in the Australian Football League (AFL) during the 1990s. Melbourne secured Ormond-Allen with the tenth pick of the 1993 AFL draft, from South Australian National Football League (SANFL) club Port Adelaide. A half-back, he broke into the seniors just once in 1995 and after playing just seven further games in 1996 was traded to Adelaide for pick 83 in the draft, Ashley Gehling. Ormond-Allen played 18 AFL games in 1997, including a semifinal and preliminary final but missed the Grand Final due to glandular fever. Adelaide made another grand final in 1998 and Ormond-Allen, despite making 15 appearances in the home and away season, once again missed out on selection. He was de-listed at the end of 2000, after not playing a senior game all season. Trent was aligned to the Port Adelaide Magpies in the SANFL when not playing AFL and won an SANFL premiership with Port Adelaide in 1998.
