The Pashtoons Social Democratic Party (known as 'Pashtuns Social Democratic Party', abbr. PSDP; ) is a political entity advocating for social democracy and the independence of Pashtuns in Afghanistan and Pakistan. It was established in February 1981 by Kabir Stori, an Afghan scholar educated in Germany and native of Kunar. The PSDP is based on the nonviolent principles of Khan Abdul Ghaffar Khan. Since April 4, 2006, Ali Khan Masood has been the incumbent chairperson of PSDP. The party does not acknowledge the Durand Line, the border division between Afghanistan and Pakistan, and instead supports the concept of a Greater ("Loy") Afghanistan.
