A curtain rod mounting assembly for mounting a curtain rod over a window includes a sleeve that is mountable to trim around a window. A pair of fasteners is each extendable through a respective one of the first and second apertures to engage the trim around the window. In this way the sleeve is retained on the trim having the sleeve is horizontally oriented. A bracket is slidably coupled to the sleeve and a receiver is removably coupled to the bracket. A hook is slidably coupled to the receiver such that the hook is spaceable a selected distance from the trim around the window thereby facilitating the hook to receive a curtain rod.
