We present for the globular cluster NGC 5927 the first multicolor
CCD photometry that reaches below the cluster's
main sequence turnoff.
The turnoff is located approximately at
, 
, 
.
There is a hint of horizontal branch morphology variations with
distance from the cluster center. Using the isochrones of
VandenBerg & Bell (1985), we derive the cluster age to be about
15 Gyr.
