Triplemanía XVII was a professional wrestling pay-per-view (PPV) event produced by the AAA promotion, which took place on June 13, 2009 at the Palacio de los Deportes in Mexico City, Mexico. It was the year an event was held under the Triplemanía chronology. Triplemanía XVII was the third Triplemanía event to take place in Mexico City, and the second to take place in Palacio de los Deportes, site of the previous Triplemanía XVI as well. The show drew close to 16.000 spectators, down from the previous years 19.000 spectators in the same venue. The Triplemanía set reduced the capacity of the arena compared to the previous year but it was not a complete sell out.
