We derive [Cu/Fe] for 117 giant stars in 10 globular clusters (M3, M4, M5, M10, M13, M15, M71, NGC 7006, NCG 288, and NGC 362) and find that globular cluster Cu abundances appear to follow [Cu/Fe] trends found in the field. This result is interesting in light of recent work, which indicates that the globular cluster ω Centauri shows no trend in [Cu/Fe] with [Fe/H] over the abundance range -2.0 < [Fe/H] < -0.8. Of particular interest are the two clusters M4 and M5. While at a similar metallicity ([Fe/H] ~ -1.2), they differ greatly in some elemental abundances: M4 is largely overabundant in Si, Ba, and La compared with M5. We find that it is also overabundant in Cu with respect to M5, although this overabundance is in accord with [Cu/Fe] ratios found in the field.
