A solar pool lamp includes a solar module and an illumination module. The solar module is electrically connected to the illumination module and supplies power to the illumination module. The solar module includes a solar module housing and a solar panel. The solar panel is disposed on the solar module housing. The illumination module includes an illumination module housing and an illumination lamp assembly. The illumination lamp assembly is mounted in the illumination module housing. The illumination module housing and the solar module housing are detachably connected. This application adopts a split structure, which allows users to easily replace illumination modules of different power or brightness. In addition, the solar power supply mode reduces the need for installing cables, plugs, and sockets, making the installation more flexible and convenient.
