The shining thicket rat (Grammomys poensis) is a species of rodent in the family Muridae.
It is found in Angola, Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Guinea, Liberia, Nigeria, Rwanda, and Uganda.
Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and subtropical or tropical moist shrubland.
The species is more commonly referred to as G. rutilans, but Musser and Carleton (2005) noted that Mus rutilans Peters, 1876 is a junior homonym of Mus rutilans Olfers, 1818, which refers to the South American Oxymycterus rutilans.
