  We present a detailed chemical abundance study of three red horizontal branch
and two red giant branch stars in the metal-rich globular cluster NGC 6637
(M69). The value of [Fe/H] derived from LTE calculations is $-$0.77 $\pm$ 0.02
dex. We also discuss the anticorrelation between oxygen and sodium abundances
in the program stars and compare the [Si/Ti] ratio of NGC 6637 with those of
other globular clusters.
