We study the prospects for detecting a light boson X with mass m(X) less than or similar to 100 MeV at a low energy electron-proton collider. We focus on the case where X dominantly decays to e(+)e(-) as motivated by recent "dark force" models. In order to evade direct and indirect constraints, X must have small couplings to the standard model (alpha(X) less than or similar to 10(-8)) and a sufficiently large mass (m(X) greater than or similar to 10 MeV). By comparing the signal and background cross sections for the e(-)pe(+)e(-) final state, we conclude that dark force detection requires an integrated luminosity of around 1 ab(-1), achievable with a forthcoming JLab proposal.
