George Henry John Bellingham (15 February 1862 – 28 July 1932) was an Australian politician who was a member of the Legislative Council of Western Australia from 1900 to 1908, representing South Province.

He served a five-year apprenticeship with an Adelaide-based surveying and engineering firm, and spent time working as a surveyor in Queensland before eventually returning to Victoria, where he was employed by Victorian Railways.

He started his own Coolgardie-based engineering business in 1893, and later also became a director of several mines in the wider Eastern Goldfields area.

Bellingham was elected as a Municipality of Coolgardie councillor in 1895, and first stood for parliament in 1897, but placed only fifth out of six candidates in North-East Province.

Bellingham was re-elected at the 1902 Legislative Council elections, but did not recontest his seat when his term expired.
