Cachoeira das Andorinhas is a waterfall located in Ouro Preto, Minas Gerais, within the Parque Natural Municipal das Andorinhas, which also forms part of the Área de Proteção Ambiental Estadual da Cachoeira das Andorinhas.

The falls drop approximately 10 meters inside a rocky formation that resembles a natural grotto, producing notably clear water. The site is recognized as the headwaters of the Rio das Velhas, the longest tributary of the Rio São Francisco.

The waterfall takes its name from the collared swifts (andorinhas de coleira) that nest in the rock formation in large numbers during spring and summer.
