Pak Kret (Thai: ปากเกร็ด, pronounced [pàːk krèt]) is a district (amphoe) in the northeastern part of Nonthaburi province, central Thailand.

It borders (from north clockwise) the districts Lat Lum Kaeo and Mueang Pathum Thani of Pathum Thani province, Don Mueang and Lak Si of Bangkok, and Mueang Nonthaburi and Bang Bua Thong of Nonthaburi.

A large oxbow of the river has been shortened by a canal, Khlong Lat Kret, dug in 1722 in the Ayuthaya Era, to form the island of Ko Kret.

Five of the tambons covering 34 villages belong to the city (thesaban nakhon) of Pak Kret.
