GALEX (Galaxy Evolution Explorer) has imaged approximately 200 globular clusters in M31 in two ultraviolet bands. We report photometry for these clusters and explore the correlation of UV color with metallicity, optical color, and horizontal branch type from HST photometry. We also compare our photometry with prior UV studies of M31 globular clusters and Galactic globular clusters. GALEX is a NASA Small Explorer, launched in April 2003. We gratefully acknowledge NASA's support for construction, operation, and science analysis for the GALEX mission. Yonsei University participation is funded by the Korean Ministry of Science & Technology, for which we are also grateful.
