Larissa O'Donovan (née Wright) (b. September 16, 1981 in Sydney, Australia) has been involved with dancing in many Wiggles productions.

She started dance at 3 years old, and studied at the Halloran School of Dance, which was one of the studios regularly used in the early Wiggles seasons. In 1996, when she was 15 years old, she auditioned for Wiggly, Wiggly Christmas and got accepted to be a Wiggles dancer. 

As a teenager, she garnered awards in Irish Dancing at the Australian National Championships. She also graduated from Brent St. Studios with a degree in Arts in 2001.

From 1998 to 2004, Larissa participated with the Wiggles cast as a Wiggly Red Coat Dancer and Tour Dancer as she got to travel throughout Australia, the United States and the world. In 2004 she left the Wiggles cast, but still showed up in a few videos, and then re-joined the cast at the end of 2006.

Her other Wiggles projects include playing Fairy Larissa in the Dorothy the Dinosaur TV series, and helping out at Mikalina's Café, which is run by Anthony Field's wife. She married Sean O'Donovan in 2008 and has two kids. Her last appearance was in Dorothy the Dinosaur TV Series 3.
