The parity-nonconserving circular polarization of ..gamma.. rays from the 2.789 ..-->.. 0.0 MeV transition in /sup 21/Ne is found to be (-9 +- 51) x 10/sup -4/, which corresponds to a parity-mixing matrix element vertical-bar < H/sub P/NC > vertical-bar = 0.009 +- 0.054 eV between the 2.80-MeV, J/sup ..pi../ = 1/2/sup + -/ levels. This value is considerably smaller than the measured parity mixing in the J = 1/2 doublet in /sup 19/F.
