Balian Buschbaum (born 14 July 1980 in Ulm, née Yvonne Buschbaum) is a German pole vaulter. Buschbaum's personal best is 4.70 metres, achieved in June 2003 in Ulm. This ranks Buschbaum second among German pole vaulters, only behind Annika Becker. On November 21, 2007 Buschbaum announced his retirement from the sport due to a persistent injury and the desire to begin gender reassignment. In January 2008, Buschbaum announced that his new first name was "Balian", after the blacksmith in the movie Kingdom of Heaven, and will begin gender reassignment surgery later that year.
