Krok Phra (pronounced as /th/) is a district (amphoe) in Nakhon Sawan province, central Thailand.
Originally, the district was named Noen Sala. However, as the old location was not convenient, the district office was moved to the west bank of the Chao Phraya River at Ban Krok Phra in 1899. The name of the district was then changed accordingly.
At first, the area was called Ban Krok which means 'village at a steep cliff'. According to the local lore, once an old rich couple from Ayutthaya wanted to move a big Buddha's image from Sukhothai to Ayutthaya on the Chao Phraya River. When it passed Ban Krok, the log broke and the Buddha image sunk into the river and could not be recovered. The residents then started calling their settlement Ban Krok Phra, adding the word phra, meaning 'venerable', to commemorate the event.
Neighboring districts are (from the north clockwise): Mueang Nakhon Sawan and Phayuha Khiri of Nakhon Sawan Province, and Mueang Uthai Thani, Thap Than, and Sawang Arom of Uthai Thani province.
Krok Phra is divided into nine sub-districts (tambons), which are further subdivided into 65 administrative villages (mubans).
