We present a catalogue of 4098 photometrically selected galaxy clusters with a median redshift <z>=0.32 in the 270deg^2^ "Stripe 82" region of the Sloan Digital Sky Survey (SDSS), covering the celestial equator in the Southern Galactic Cap (-50{deg}<RA<59{deg}, |DE|<=1.25). Owing to the multi-epoch SDSS coverage of this region, the ugriz photometry is ~2mag deeper than single scans within the main SDSS footprint. We exploit this to detect clusters of galaxies using an algorithm that searches for statistically significant overdensities of galaxies in a Voronoi tessellation of the projected sky.
