Attock Fort (Punjabi: قلعہ اٹک / ਅਟੌਕ ਕਿਲ੍ਹਾ ) is a fortress in Pakistan, built at Attock Khurd during the reign of Akbar from 1581 to 1583 under the supervision of Khawaja Shamsuddin Khawafi to protect the passage of the River Indus.

[1] Ahmad Shah Durrani recaptured Attock and halted the Maratha advance in the north temporarily after the Third Battle of Panipat.

Construction was completed in two years after which the fort was used as a key defense line against Afghan invaders.

The fort was captured in 1758 by Tukojirao Holkar and Sabaji Shinde Sidhojiraje Ghatage-Desai-Deshmukh, aka Manaji Paygude (the conqueror of Lahore), and the Marathas.

In the 1830s, the Sikhs strengthened the fort by constructing 'very high and massy bastions' at each gate.
