  We present the discovery of CLASS B0739+366, a new gravitational lens system
from the Cosmic Lens All-Sky Survey. Radio imaging of the source with the Very
Large Array (VLA) shows two compact components separated by $0\farcs54$, with a
flux density ratio of $\sim$ 6:1. High-resolution follow-up observations using
the Very Long Baseline Array (VLBA) at 1.7 GHz detect weak, parity-reversed jet
emission from each of the radio components. Hubble Space Telescope NICMOS F160W
observations detect infrared counterparts to the lensed images, as well as an
extended object between them which we identify as the lensing galaxy. Redshifts
for the galaxy and lensed source have not yet been obtained. For typical lens
and source redshifts of $z=0.5$ and $z=1.5$, respectively, preliminary mass
modeling predicts a time delay of $\sim7h^{-1}$ days in a flat $\Omega_{M}=1.0$
universe. The small predicted time delay and weak radio components will make
CLASS B0739+366 a challenging target for Hubble constant determination.
