Danell Johan Leyva (born October 30, 1991) is a Cuban-American gymnast who competed for the United States. He is the 2012 Olympic individual all-around bronze medalist and 2016 Olympic parallel bars and horizontal bar silver medalist. He is also the 2011 U.S. national all-around gold medalist and the 2011 world champion on the parallel bars.
Leyva is a specialist on parallel bars and horizontal bar, having his own signature move (jam-dislocate-hop to undergrips) on the latter.
Leyva has a sister, Dayanis Mesa, who is a television host. His stepfather and coach, Yin Alvarez (famous for his sideline theatrics during Danell's routines) and mother, Maria Gonzalez (his biological father, Johann Leyva, lives in Spain), were both members of Cuba's national gymnastics team. Gonzalez and Leyva defected to Miami when Leyva was a year old. Alvarez defected by swimming across the Rio Grande to the United States while his team was competing in Mexico. Together, Alvarez and Gonzalez opened a gym in Miami several years later, and they married in 2001.
