Andrew Otten (born 15 May 1989) is a former professional Australian rules football player who played for the Adelaide Football Club in the Australian Football League (AFL).
Otten was Adelaide’s second selection in the 2007 National Draft, pick 27 overall, having recorded strong results at the 2007 NAB AFL Draft Camp ranking in the top 2% for the vertical leap (92cm), top ten for agility and the top 20% for the beep test (14.2).
Otten made his debut in round 12 against eventual premiers Hawthorn, and played one more game for the 2008 season. The next season, he exploded onto the AFL scene, playing a consistent running role across half back and being likened to former defender Nathan Bassett. Otten won an AFL Rising Star nomination in round 9 for his performance against Carlton, in which he collected 23 possessions and kicked a goal, and at the end of the season was voted the runner-up in the ward to Daniel Rich. Otten also scored three votes in the 2009 Brownlow Medal count.
