This paper proves the existence and uniqueness of quadratic mean almost periodic mild so- lutions for a class of stochastic dierential equations in a real separable Hilbert space. The main technique is based upon an appropriate composition theorem combined with the Banach contraction mapping principle and an analytic semigroup of linear operators.
