Preah Pithu (Khmer: ប្រាសាទព្រះពិធូរ, Prasat Preăh Pĭthu [praːsaːt prĕəh pi tʰuː]) is a group of five temples at Angkor, Cambodia.

The five temples are in bad conditions, upper levels are ruined, but their carvings are interesting and the site is rather peaceful, wooded and scarcely crowded.

The fragments of the lintel of western door, on the ground, show a stylized depiction of the "Churning of the Sea of Milk", while the walls are decorated with devatas and floral motifs, Bayon style.

The internal walls are sculpted with dvarapalas and the blind arches at the base of pillars are typical of Angkor Wat period.

On the West it has a causeway which ends with a 40 meter long cruciform terrace, leading into NE corner of the Royal Square.

Its sanctuary chamber, standing on two-tier sculpted basement, is the largest of the group, having a square side of 3.80 m, and hosting a large 1.5 m linga.

The larger chamber has mostly collapsed, but on its western side there are two remarkable half-frontons, which depict the defeat of the asura Bana by Krishna to the north and the three giant steps of Vamana to the south.
