Eric Paul Decker (22 November 1896 – 7 July 1970) was an Australian politician and real estate agent.

He joined the First Australian Imperial Force in 1916, and was appointed a lance corporal in June 1917 and wounded in August 1917.

On 18 September 1926 he married Eden Templeton Kemp (died 1990)[2] and together had a son and a daughter.

A keen fisherman, Decker and a friend, George Mulvena, were fishing off Sandgate when their dinghy capsized and both men drowned.

He represented Sandgate until the 1953 Queensland state election where in a surprise result was beaten by Labor candidate Herbert Robinson.
