Pak Kret (, ) is a district (amphoe) in the northeastern part of Nonthaburi province, central Thailand. The district is most notable for Muang Thong Thani, Ko Kret and Central Chaengwattana. The MRT Pink Line and Udon Ratthaya Expressway serves part of the district.
The district is in the northeast of the province. 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.
The Chao Phraya River crosses the district. A canal has shortened a large oxbow of the river, Khlong Lat Kret. It was dug in 1722 in the Ayuthaya Era to form the island of Ko Kret.
The district is divided into 12 sub-districts (tambons). These are further subdivided into 85 villages (mubans).
Five of the tambons covering 34 villages belong to the city (thesaban nakhon) of Pak Kret. Bang Phlap itself has had township (thesaban tambon) status since 2013. The other six tambons are each administered by a Tambon Administrative Organization (TAO).
