The Thirteenth Amendment to the Constitution of Pakistan (Urdu: آئین پاکستان میں تیرہویں ترمیم) was a short-time amendment to the Constitution of Pakistan, adopted by the elected Parliament of Pakistan in 1997 by the government of people elected Prime Minister Nawaz Sharif.

The amendments removed nearly all institutional checks and balances on the Prime Minister's power, by effectively removing the legal remedies by which he could be dismissed.
