We present a compactness criterion in ideal spaces of vector-valued functions. In the case of real functions, the criterion gives a precise formula for the measure of non-compactness. In the Lebesgue-Bochner spaces the result can be interpreted as a Riesz compactness criterion and generalizes a theorem of Orlicz and Szufla.
