Courtney Morantz is a character portrayed by Carrie Southworth in the ABC crime series Castle. Courtney was the fiancée of Doctor Joshua Leeds, a plastic surgeon. The two apparently had a very deep relationship, Courtney showing obvious grief at his death, and reflecting that he would always call her if circumstances meant that he would be late. Although she identified his body, Courtney was unable to provide the team with any information about what Leeds might have been involved in that would have resulted in his death.
