Maria Catalano

Maria Catalano (born 27 February 1982) is an English snooker player from Dudley. She began playing snooker at 15 and received coaching from her first cousin, professional player Ronnie O'Sullivan. She made her World Women's Snooker Tour debut in 1998 and went on to win 11 women's ranking titles, including the 2007 British Women's Open and the 2012 UK Women's Championship. A five-time runner-up at the World Women's Snooker Championship, she was ranked number one in the women's world rankings during the 2013–14 season. With Reanne Evans, she won the World Women's Pairs Championship in 2018. She reached the final stages of the World Seniors Championship in 2022, becoming the first female player to do so.

After transgender player Jamie Hunter won the inaugural US Women’s Open in August 2022, Catalano ceased competing to protest World Professional Billiards and Snooker Association policies permitting transgender players to enter women's tournaments. In 2025, after the WPBSA announced that it would review its stance on transgender competitors, Catalano said that she would return to the sport if the rules were changed.
