We present kinematic evidence for a rapidly rotating circumstellar disk around the young stellar object WL 16, based on new high velocity resolution data of the v = 2-0 CO bandhead emission. A Keplerian disk provides an excellent fit to the observed profile, with a projected velocity v sin i = 140 km s(-1) at the outer disk edge and about 250 km s(-1) at the inner edge. The disk must extend to within one stellar radius or less of the stellar surface. Constraints on the stellar mass of WL 16 and on other properties of the inner disk are discussed.
