Fabiana de Almeida Murer (born 16 March 1981) is a retired Brazilian pole vaulter. She holds the South American record in the event with an indoor best of 4.82 m and an outdoor best of 4.87 m, making her the fourth highest vaulter ever at the time, now the eighth. She won the gold medal at the 2011 World Championships in Athletics, at the 2010 IAAF World Indoor Championships and also won at the 2007 Pan American Games. Murer represented Brazil at the 2008, 2012 and 2016 Summer Olympics. She is a four-time South American Champion with wins in 2006, 2007, 2009 and 2011. Murer was coached by both the Ukrainian Vitaly Petrov, who managed the world record holders Sergei Bubka and Yelena Isinbayeva, and her husband, Élson Miranda de Souza, a former vaulter himself.
Murer set an outdoor personal best of 4.80 metres in June 2008 in São Paulo. This was a South American record. She finished tenth at the 2008 Summer Olympics with a vault of 4.50 m, unable to scale the heights that she had in June. During the competition, the organization lost one of Murer's poles, causing her to underperform as she spent over 10 minutes trying to get the pole back.
