Iyo ang Tondo, Kanya ang Cavite () is a 1986 Filipino action film directed by Pablo Santiago from a screenplay by Agustin B. de la Cruz, starring Fernando Poe Jr. and Ramon Revilla.
The film earned less at the box office than what its producers anticipated, with industry observers assuming that GMA Network's television broadcasts of past Poe films had likely drawn audiences away from watching Poe's new films in cinemas.
Crisanto (Poe) is a valiant man from the streets of Tondo beloved by its people for his acts of vigilantism and his Robin Hood-like generosity to its poor. Bador (Revilla), on the other hand, is an influential man in Cavite's underworld whose tight grip is recognized in the entire province. Crisanto and Bador are good friends dating back to their incarceration at the New Bilibid Prison.
Their friendship will be put to the ultimate test as the Kingpin of Tondo is pitted against his staunch ally, the Don of the Cavite gangland, by a cabal of men from both Tondo and Cavite eager to oust both from their respective thrones. Now the best of friends become the worst of enemies as Tondo collides with Cavite.
The BSH Films-produced film was released on January 30, 1986
The film earned less at the box office than what its producers expected. Observers of the film business suggested that it is likely due to GMA Network having started to broadcast Poe's past films through the television program FPJ sa GMA, which may have drawn audiences away from watching Poe's new films in cinemas. Another reason given was Poe's politics: Poe supported the reelection of President Ferdinand Marcos in the 1986 snap elections, which may have affected his popularity among his viewers.
