Lake Zirahuén is a small endorheic lake in the municipality of Santa Clara del Cobre in Michoacán, Mexico.

It is a deep mountain lake with a sandy bottom that is partially covered with mud.

[1] It covers an area of 970 hectares (2,400 acres) and has a volume of 0.216 cubic kilometres (0.052 cu mi).

[2] At times Lake Zirahuén has been part of an open and continuous hydrological system together with Lake Cuitzeo and Lake Pátzcuaro, draining into the Lerma River.

Today it is a closed basin like Lakes Cuitzeo and Pátzcuaro, although ecologists consider it a sub-basin of the Lerma-Chapala basin.
