Gordon Peter Campbell (October 3, 1898 – January 16, 1964) was a Canadian Senator, lawyer and businessman.

A lawyer by profession, he was senior partner at the Toronto firm of Campbell, Godfrey and Lewtas.^[1]

Campbell was a senior fundraiser for the Liberal Party of Canada^[2] and managed the party's financial affairs during the 1940 federal election.^[1]

In the 1930s he founded the Centurian Club, a non-partisan service organization with a mandate to interest young people in politics.^[1]

Campbell was born in Ridgetown, Ontario. As a youth, he earned pocket money by working in the general store and operating a dance hall with friends that, on one occasion, featured a young Guy Lombardo conducting the orchestra.^[1]

He graduated from Osgoode Hall Law School in 1923 and became a junior partner in the Toronto firm of Arnoldi, Parry and Campbell. He initially focussed on litigation but later switched to corporate and taxation law.^[1]

He became particularly involved with maritime law^[2] and served as counsel to the Lake Shipping Association and the East Elevators Association.^[1] He was one of the first proponents of offshore radio, and recommended that commercial radio stations be established off the coasts of Canada.

In the 1930s, he played a role in the drafting of the Canada Shipping Act of 1934, Canada's first attempt to regulate the shipping industry which had previously been regulated by laws inherited from Britain.^[1][2]

He was named King's Counsel in 1939.^[1]

Campbell was appointed to the Senate by William Lyon Mackenzie King in 1943 and sat in the chamber as a Liberal until his death at the age of 65.
