We use the catalog of stellar clusters selected from the Panchromatic Hubble Andromeda Treasury: Triangulum Extended Region (PHATTER) survey. We analyze 711 clusters in M33 with $\\rm 7.0 < log(Age/yr) < 8.5$, and log($M/M_{\\odot}$) $>$ 3.0 as determined from color-magnitude diagram fits to individual stars. The M33 cluster mass function is best described by a Schechter function with power law slope $\\alpha = -2.06^{+0.14}_{-0.13}$, and truncation mass log($M_c/M_{\\odot}$) $= 4.24^{+0.16}_{-0.13}$.
