Stuart Charno (born 29 September 1956; age 56) is an American actor from Queens, New York. For Star Trek, however, he co-wrote the stories for three episodes of The Next Generation along with his then-wife, Sara Charno. This is the extent of his writing credits.

This was followed in 1985 with what may be his best known role as Harold "Reptile" Sherpico in the comedy Just One of the Guys, co-starring Katy Boyer, Leigh J. McCloskey, Clayton Rohner, and Kenneth Tigar. The following year, he and Clayton Rohner also appeared in Modern Girls, starring Virginia Madsen, Cameron Thor, and Mark Holton. His other film credits include Young Doctors in Love (1982, with Ed Begley, Jr., Hamilton Camp, Deborah Lacey, Michael McKean, and Saul Rubinek), John Carpenter's Christine (1983, with Bruce French), Hard to Hold (1984, with Gregory Itzin), Once Bitten (1985), and Stephen King's Sleepwalkers (1992, with Mädchen Amick, Alice Krige, Frank Novak, and Ron Perlman).
On television, Charno has appeared on M*A*S*H (starring David Ogden Stiers), Buffalo Bill (starring Joanna Cassidy and John Fiedler), Newhart, The X-Files, and Profiler (with Raphael Sbarge). He also had a recurring role in the hospital television drama Chicago Hope, during which he worked with fellow Trek performers Seymour Cassel, Rosemary Forsyth, and Anne Elizabeth Ramsay.
