Lewis Jetta (born 4 May 1989) is a former Australian rules footballer who played for the Sydney Swans and West Coast Eagles in the Australian Football League (AFL).

Jetta played his junior football with Carey Park Junior Football Club, a Bunbury side in the South West Football League (SWFL), before playing for Western Australian Football League (WAFL) club Swan Districts and was a part of the colts premiership in 2007.

He was overlooked in the 2007 AFL draft and decided to return to his hometown Bunbury to play for Bridgetown Football Club in the Lower South West Football League. After one season with Bridgetown Lewis returned to Swan Districts to play senior football in 2009.

Jetta was drafted by Sydney with the 14th selection in the 2009 AFL draft, which had been traded from Collingwood in exchange for Darren Jolly.

Jetta is a small, but extremely quick and skilful player who was overlooked in both the 2007 and 2008 drafts, before having a breakthrough year for Swan Districts in 2009. He represented Western Australia in their state game against South Australia in June 2009 and kicked three goals, including the WA's last goal in the final minutes. He is the cousin of Neville Jetta who plays for Melbourne and his brother Graham Jetta plays for Swan Districts.

Jetta was impressive against Carlton in the opening round of the 2010 NAB Cup.^{[citation needed]}

In 2010, Jetta's debut season, he scored 19 consecutive behinds without a goal. In round 19, against Hawthorn at the Sydney Cricket Ground, he kicked his first goal late in the game to break his streak and received a standing ovation from the crowd.

Jetta came third in the 2010 AFL Grand Final sprint, representing Sydney.
