University of Oklahoma Observatory is an astronomical observatory. It is located in Norman, Oklahoma on the campus of the University of Oklahoma. Built in 1939, with a 10-inch Newtonian reflector and a smaller 3.5-inch telescope, it was housed in a 16-foot dome atop what was at the time the southernmost building on campus. In 1995, the original 10-inch telescope was replaced by a 0.4 meters Meade SCT.
