Viva Seifert (born 15 April 1972) is a British musician and former gymnast. She began her career as a competitive rhythmic gymnast, and competed at the 1992 Summer Olympics. Following a number of television appearances, which include performing with the WeatherGens, she made her musical debut as a member of the band Bikini Atoll—active from 1999 to 2006—where she performed as a keyboardist.

The band has released two albums: Harum Scarum in 2010 and Freakish in 2013, with the former enjoying critical success. In 2015, she starred in the leading role of Hannah Smith in the indie video game Her Story, which earned her the Game Award for Best Performance and the Great White Way Award for Best Acting in a Game among others, and acclaim from several critics and publications.

In 2021, Seifert co-founded the independent musical duo Lunge (stylized in all caps) with her husband Mark "Arp" Cleveland.
