Phnom Krom (Khmer: ភ្នំក្រោម) is a 140 m high hill close to Siem Reap city, Cambodia and there is a temple located on the top which derived its name from the hill, "Prasat Phnom Krom" (Khmer: ប្រាសាទភ្នំក្រោម). Prasat means "temple".

There is an Angkorian temple named " Prasat Phnom Krom " which is located on top of the hill. It is a Hindu shrine dedicated to Shiva, Vishnu and Brahma.

The temple was built at the end of the 9th century, during the reign of King Yasovarman (889 A.D.-910 A.D.).

Oriented toward the east, the hilltop temple is enclosed by a wall built of laterite blocks. Along the walls' top runs a cornice. Gates bisect the walls at each of the four cardinal directions. Just inside the east gate are four small buildings arrayed in a north-south row, possibly formerly used as crematoria. Inside the walls on the north and south sides are three halls, now collapsed. The temple’s focus is three towers, also in a row running north to south. They sit atop a platform reached by staircases of seven steps. The southern tower is dedicated to Brahma, the central to Shiva, the northern to Vishnu. Unusually, the three other two sides, Its layout is identical to Phnom Bok which must have been built at the same time.

They were built of sandstone; much of their carving and detail has been lost to erosion including, the lintels in very poor condition, feature garlands and inward-facing makaras. Octagonal colonettes decorate the doorways.

Phnom Krom is the southernmost of three hilltop temples built in the Angkor region during the reign of Yasovarman. The other two are Phnom Bakheng and Phnom Bok.
