Mirna Sucely Ortiz Flores (born 28 February 1987) is a Guatemalan racewalker. Having begun in the sport in 1998, she won a Central American youth title in 2000, and was a promising young athlete in her discipline, but due to financial hardship, she had to abandon the sport at the age of 14. She then returned to a competitive level in 2011, urged by coach . Her return proved to be fruitful as in September 2011 she earned second place in the National Polish Championship in Varsovia, thereby qualifying for the 2012 Olympic Games, and a few weeks later she won the silver medal at the 2011 Pan American Games, behind her compatriot Jamy Franco in a race they both led from start to end.
