Maria Cioncan (19 June 1977 - 21 January 2007) was a middle distance runner from Romania, best known for winning a bronze medal in the 1500 metres event at the 2004 Summer Olympics.
Born in Maieru, she set personal bests in both 800 and 1500 metres during the games. Her 2005 season was cut short, and her only notable competition appearance was at the SPAR European Cup in Firenze, Italy where she won the 800 (2:00.88) and placed second in the 1500 (4:07.39). Cioncan's last competition on the top international level was the 2006 World Indoor Championships, where she failed to progress past the first heat of the 800m. Earlier that indoor season she ran an indoor personal best of 2:01.70.
On 21 January 2007 Cioncan died in a car accident near Pleven, Bulgaria. She was returning from a training camp in Greece when her vehicle flipped over and struck a tree, killing her instantly.
