Ebenezer "Eben" Allen (15 November 1868 – 20 May 1931) was an Australian businessman and politician who was a member of the Legislative Assembly of Western Australia from 1911 to 1917, representing the seat of West Perth.

He first ran for parliament at the 1908 Legislative Council elections, but lost to Arthur Jenkins in Metropolitan Province.

Allen recontested West Perth at the 1921 election, but polled only the third-highest number of votes.

Draper lost his seat regardless, with the winning candidate, Edith Cowan, becoming the first female member of parliament in Australia.

He killed himself with a gunshot to the head on the Perth Esplanade, having had business troubles and been in poor physical health.
