San Bartolomé Quialana is a town and municipality in Oaxaca in south-western Mexico.

It is part of the Tlacolula District in the east of the Valles Centrales Region.

Municipal President Victorino Gómez Martínez died on August 25, 2020 during the COVID-19 pandemic in Mexico.

This is associated with the fact that there is a rocky hill in the area which is called Picacho or Yubda (in Zapotec, "Sun Rock).
