Boquerón is a Cuban village and consejo popular ("people's council", i.e. hamlet) of the municipality of Caimanera, in the Province of Guantánamo.

Located near Guantánamo Bay, it is also known as Mártires de la Frontera, Spanish for "Martyrs of the Border".

The North East Gate (19°58′26″N 75°05′13″W / 19.97382°N 75.08692°W / 19.97382; -75.08692), located 4 km (2 miles) from it, is the only US-Cuban border crossing point.

[1][2] Due to its proximity to the US Base Boquerón is, along with Caimanera, a forbidden town needing a special permission from the government to visit it.

The village is the southern terminal of a minor railway line from Guantánamo and counts a little port.
