Plaza Egaña is an underground metro station on the Line 4 of the Santiago Metro, in Santiago, Chile. It is located under Egaña Square.

The cross-section of the platform-level tunnel has the shape of two partially intersecting circles, which was so designed due to the predominant presence of clay in the surrounding soil.^[2] Support columns of 1.1 m (3 ft 7 in) in diameter separate the tracks from each other.^[2] The platforms have 140 m (460 ft) long.^[2]
