Ongkharak (Thai: องครักษ์, pronounced [ʔōŋ.kʰā.rák]) is a district (amphoe) in the western part of Nakhon Nayok province, central Thailand.

Once King Chulalongkorn (Rama V) visited Mueang Nakhon Nayok. When he and his company arrived in the area of Ongkharak District, one of the royal guard fell ill and died. The king ordered a shrine built to commemorate his servant. Ongkharak means 'royal guard'.
