Protests in Afghanistan against the Taliban started on 17 August 2021 following the Fall of Kabul to the Taliban. These protests are held by Islamic democrats and feminists. Both groups are against the treatment of women by the Taliban government, considering it as discriminatory and misogynistic. Supported by the National Resistance Front of Afghanistan, the protesters also demand decentralization, multiculturalism, social justice, work, education, and food. There have been pro-Taliban counterprotests.

The National Resistance Front of Afghanistan (NRF), also known as the Second Resistance, is a military alliance of former Northern Alliance members and other anti-Taliban fighters loyal to the Islamic Republic of Afghanistan. The founder and president of NRF is Ahmad Massoud. When the Taliban captured Afghanistan on 15 August 2021, former first vice president Amrullah Saleh, citing provisions of the 2004 Constitution, declared himself the caretaker president of Afghanistan and announced the republican resistance against the Taliban. Saleh's claim to the presidency was endorsed by Ahmad Massoud, as well as by former Afghan Minister of Defence Bismillah Mohammadi, and the Afghan embassy in Tajikistan including its ambassador Mohammad Zahir Aghbar.
