We observed the position of the superluminous supernova PS15ae (=CSS141223-113342+004332 = MLS150211-113342+004333) with the Very Large Array on 2015 December 11.67 (UT) when the VLA was in D configuration. We did not detect the source and set a 3-sigma upper limit of 40 microJy at a mean frequency of 21.85 GHz. This corresponds to a luminosity of Lnu ~ 1.3e28 erg/s/Hz at the redshift of the SN (z=0.11), assuming standard LCDM cosmology. This is the most restrictive radio upper limit to date for a superluminous SN.
