Ranot (Thai: ระโนด, pronounced [rā.nôːt]) is the northernmost district (amphoe) of Songkhla province, southern Thailand.

The name Ranot is a Thai corruption of Renut (Jawi: رينوت), its original name in Malay.

However, many local residents maintain that it is a shortened form of the Thai words ราวโตนด (rao tanot: 'a row of palm trees').

The district is divided into 12 sub-districts (tambons), which are further subdivided into 73 villages (mubans).

Ranot covers parts of tambon Ranot, and Bo Tru covers parts of tambons Bo Tru, Ra Wa, and Wat Son.
