Jana Komrsková (born 6 May 1983 in Roudnice nad Labem) is an artistic gymnast from the Czech Republic who competed in the 2000 and 2004 Summer Olympics.

In the Olympic year, Komrsková recorded her first success in a World Cup competition (second place on vault in Cottbus, behind Russia's Yelena Produnova) and finished ninth in the all-around at the 2000 European Championships.

Komrsková qualified for the individual all-around final in 29th place despite an infection contracted through blisters on her forearm.

[1] After the Games, Komrsková placed fourth on uneven bars and vault at the World Cup final in Glasgow.

At the 2003 Worlds in Anaheim, California, she clinched the only Czech berth for the 2004 Summer Olympics, but injured her elbow in the process.

Komrsková was the highest-scoring Czech gymnast at the 2006 World Championships and narrowly missed the all-around final: She finished 32nd in qualifications, making her the second alternate.

At the 2007 World Championships in Stuttgart, she finished seventh on vault, with high execution marks but relatively low difficulty.
