Tan Gee Paw DUBC PJG (born c. 1944) is a Singaporean former bureaucrat who served as chairman of the Public Utilities Board from 2001 to 2017.

Tan grew up with numerous extended relatives in a bungalow in Waterloo Street and attended Anglo-Chinese School.

Shortly after establishing the Water Planning Unit in the Prime Minister's Office in 1971, Prime Minister Lee Kuan Yew tasked Tan and the Permanent Secretary of the Ministry of the Environment, Lee Ek Tieng, with drafting Singapore's first water master plan.

The Cabinet of Singapore quickly approved of their S$100 million programme, which led to a significance decrease in the incidence of floods nationwide.

Tan, Lee Ek Tieng, and eight other civil servants who were involved in the cleanup were each presented with a solid gold medal at a Clean River Commemoration ceremony on 2 September 1987.
