Phu Ruea (Thai: ภูเรือ), is a 1365 m high mountain in Loei province, Thailand.

The peak rises seven kilometers north of Highway 203, between Loei town and Phetchabun.

[1] The name of the mountain comes from the fact that it looks like an upside down boat (Thai: เรือ) from certain angles.

The park borders Sainyabuli province in Laos at its northern end.
