There is a colony of introduced macaques in Silver Springs State Park, Florida, USA. These monkeys have been there since the 1930's. Monkeys also inhabit several other areas in the state of Florida; a colony of around 40 vervet monkeys persists south of Fort Lauderdale.
IMO this should not include introduced populations and you could argue any feral monkeys are introduced. There are several feral populations through many Northern Hemisphere countries for example.
So those on Maldives, many of the Caribbean islands etc. really shouldn’t count.
