Urxvt is a rxvt-unicode (Urxvt for short) terminal emulator for the X Window System, also available for Windows in the form of a Cygwin port.
RXVT was originally written by Rob Nation and later extensively modified by Mark Olesen, who took over maintenance for several years. It is intended to be a slimmed-down alternate for xterm, omitting some of its little-used features.
The latter refers to the Xt resource mechanism, e.g., for binding keys. rxvt is an extended version of the older xvt terminal emulator by John Bovey.
The name originally stood for "Rob's xvt" (with XVT stands for 'X Virtual Terminal'), but was later re-dubbed "our xvt" (pronounced like the letters r-x-v-t).
