Kacy Esther Catanzaro (born January 14, 1990) nicknamed Mighty Kacy, is an American gymnast and athletics-based television personality. She is noted for being the first woman to qualify for the finals of the television sports challenge American Ninja Warrior and the first, and so far only, woman on it to complete a City Finals course (in 2016 Jessie Graff finished second on a City Finals course based on 'the farthest the fastest' but did not complete it).
