John William Causey (September 19, 1841 – October 1, 1908) was an American politician, lawyer and farmer from the state of Delaware. He was a member of the Democratic Party who served as a state senator and as a member of the U.S. House of Representatives.

Causey was born in Milford, Delaware, attended a private school, The Albany Academy in Albany, New York, and was graduated from the Pennsylvania Agricultural College.

A Democrat, Causey was elected to the Delaware State Senate for 1875–1877 and was a delegate to the Democratic National Convention in 1884. President Grover Cleveland appointed him an internal-revenue collector for Delaware in 1885, and he served in that capacity until 1887. He served in the U.S. House of Representatives from March 4, 1891, until March 4, 1895, but was not a candidate for renomination in 1894.

Causey died at Milford and is buried there in the Odd Fellows Cemetery.
