Montero Hoyos is a small town in the Santa Cruz Department in the South American Andean Republic of Bolivia.

Montero Hoyos is located 51 kilometers north-east of the departmental capital Santa Cruz.

From Santa Cruz the tarmac road Ruta 4/Ruta 9 goes east through Cotoca and Puerto Pailas before it crosses the Río Grande and reaches Pailón on the river's eastern banks.

At Puerto Pailas, a dirt road leaves the Rutas 4/9 in north-westerly direction for another 4 km to Montero Hoyos.

The population of the place has increased rapidly over the past two decades.
