Pristimantis orcesi is a species of frog in the family Strabomantidae.

[1][3][4] The specific name orcesi honors Gustavo Orcés [es], an Ecuadorian naturalist.

The fingers and toes bear lateral fringes as well as discs at their tips.

[2][6] Pristimantis orcesi is associated with terrestrial bromeliads and rocks in dry páramo grassland at elevations of 3,160–3,800 m (10,370–12,470 ft) above sea level near small steams that retain some moisture.

It is known from the Llanganates and Sangay National Parks and its range overlaps with some other protected areas.
