Wang Chan (Thai: วังจันทร์, pronounced [wāŋ t͡ɕān]) is a district (amphoe) in the northern part of Rayong province, eastern Thailand.

The minor district (king amphoe) Wang Chan was created on 16 November 1977 by splitting off the two tambons Chum Saeng and Wang Chan from Klaeng district.

[2] Neighboring districts are (from the east clockwise) Khao Chamao, Klaeng, Mueang Rayong, Ban Khai and Pluak Daeng of Rayong Province, and Nong Yai and Bo Thong of Chonburi province.

The district is divided into four sub-districts (tambons), which are further subdivided into 30 villages (mubans).

Chum Saeng is a township (thesaban tambon) which covers parts of tambons Chum Saeng and Phlong Ta Iam.
