Shighnan, also Shignan, Shugnan, Shughnan, and Khughnan (Tajik: Шуғнон, Persian: شغنان, Pashto: شېرخان بندر, Shughni: خُږنۈن, Хуг̌ну̊н, Xuɣ̌nůn), is an historic region whose name today may also refer to a town and a district in Badakhshan Province in the mountainous northeast of Afghanistan and also a district in Gorno-Badakhshan Autonomous Province in Tajikistan.

The administrative center of the Shighnan District of Afghanistan is called Qaleh Barpanjeh (قلعه برپنجه).

These villages include, south to north, Darmarakht, Wiyod, Wiroodhj, Bashor, Vuzh-Pidrudh, Dhishahr, Shidwood, and Tsaghnod.

Some of the bigger villages in the Tajik side of Shughnan include, south to north, Darmarakht, Porshnev, Buni, Sokhcharv, and Rosht Qala.

The Russian-controlled half of Shughnan was incorporated into the Gorno-Badakhshan oblast in 1925, which was merged into the newly formed Tajikistan in 1929.
