We have determined Al, $\alpha$, Fe-peak, and neutron capture elementalabundances for five red giant branch (RGB) stars in the Galactic globularcluster M10. Abundances were determined using equivalent width analyses ofmoderate resolution (R$\sim$15,000) spectra obtained with the Hydra multifiberpositioner and bench spectrograph on the WIYN telescope. The data sample theupper RGB from the luminosity level near the horizontal branch to about 0.5 magbelow the RGB tip. We find in agreement with previous studies that M10 ismoderately metal-poor with [Fe/H]=-1.45 ($\sigma$=0.04). All stars appearenhanced in Al with $<$[Al/Fe]$>$=+0.33 ($\sigma$=0.19), but no stars have[Al/Fe]$\ga$+0.55. We find the $\alpha$ elements to be enhanced by +0.20 to+0.40 dex and the Fe--peak elements to have [el/Fe]$\sim$0, which areconsistent with predictions from type II SN ejecta. Additionally, the clusterappears to be r-process rich with $<$[Eu/La]$>$=+0.41.
