Tatiana Chişca (born July 19, 1995 in Bălți) is a Moldovan swimmer, who specialized in breaststroke events. Chisca qualified for the women's 100 m breaststroke at the 2012 Summer Olympics in London by breaking a Moldovan record and eclipsing a FINA B-standard entry time of 1:10.68 from the Ukrainian Championships in Dnipropetrovsk. She challenged seven other swimmers on the second heat, including two-time Olympian Danielle Beaubrun of St. Lucia. Chisca rounded out the field to last place by more than two seconds behind Chinese Taipei's Chen I-Chuan in 1:13.30. Chisca failed to advance into the semifinals, as she placed fortieth overall in the preliminaries.
