We evaluate for the first time the η^′ p femtoscopic correlation function to study the η^′ N interaction. We find it extremely sensitive to the value of the η^′ p scattering length, for which at present there exists only very limited information, not even knowing its sign. The measurement of this correlation function would provide much valuable information on the η^′ N interaction, which could then also be used to settle the issue of possible η^′ nucleus bound states, an issue attracting much attention in the nuclear physics community.
