The Costa Mujeres centre is an extension of Nadal's original academy based on his native Mallorca.
"We've been coming here for many years and we know the area," said
the 11-time French Open champion at a press conference in Cancun on
The tennis centre includes eight floodlit clay courts, a paddle court, gymnasium and a sports clothing and equipment store.
Although the centre will initially cater to tourists and locals,
Nadal said "one of the medium- and long-term aims is to contribute to
the development of tennis in Mexico".
Mexico's most successful ever player was Rafael Osuna, a former world number one who claimed the US Open title in 1963.
Osuna also won three Grand Slam doubles titles and the Olympic doubles gold medal in 1968 when tennis was a demonstration event.
He helped Mexico to the 1962 Davis Cup final, their only ever appearance in the team competition championship decider.
Osuna died in a plane crash in Mexico in 1969, aged 30.
World number two Nadal is due to play in the Acapulco Open next week,
an event he has won twice before although he had to pull out before his
first match last year due to injury.
