Longxu District is a district located within the prefecture-level city of Wuzhou in the Guangxi Zhuang Autonomous Region of China. It was officially established in March 2013 following an administrative restructuring that involved splitting four towns from Cangwu County.
The district takes its name from Longxu Town, which serves as the district seat. Historically, Longxu Town functioned as the seat of Cangwu County before the 2013 reorganization moved the county seat to Shiqiao Town.
