Katja Demut (born 21 December 1983) is a German track and field athlete who specialises in the triple jump.
Born in Schmölln, she began competing in the event as a teenager, representing the TuS Jena club.
That year she had won at the 2009 German Athletics Championships, improved her indoor best to 14.06 m and set an outright best of 14.20 m outdoors in Ulm.
[3] Demut hit a new career high in 2011: she broke Petra Laux-Lobinger's German indoor record in Chemnitz with a clearance of 14.45 m and took it two centimetres further at the PSD Bank Meeting.
[7] She was set to be a contender at the 2011 World Championships in Athletics, but a heel injury four days before the competition forced her to withdraw and bring her season to a close.
