Krol Ko in Angkor, Cambodia, is a Buddhist temple built in the late 12th century under the rule of Jayavarman VII. It is north of Neak Pean.

Krol Ko is a small temple located north of Neak Pean. It may have served as a chapel in a hospital location, as its layout is identical to the four hospital chapels found outside Angkor Thom (the "Hospital Chapel" to the east, Ta Prohm Kel to the south, Tonle Sgnout to the north, and another location now in ruins to the west). The placement of a hospital near Neak Pean would have felt like Neak Pean was built as a representation of the waters of the mythical lake Anavatapta, which were thought to cure diseases. More revealing, seven of the temple pediments in Krol Ko feature Lokeshvara, the healing bodhhattattva, commonly associated with hospitals. The name 'Krol Ko' is a modern term meaning 'The Park of the Oxen' and probably has no connection with its historical use.
