Maret Ani (born 31 January 1982) is an Estonian tennis player. At the start of 2006, she was the top-ranked player in Estonia, before losing that spot to Kaia Kanepi.
Ani was a junior basketball champion, but devoted herself to tennis from the age of 14. She moved to Italy three years later after finding sponsorship for coaching. She was coached initially by Aita Põldma and later by Pierfrancesco Restelli.
Ani first played for the Estonia Fed Cup team in 1998.
