Sao Hai (Thai:เสาไห้,pronounced[sǎwhâj]) is a district (amphoe) inSaraburi province, centralThailand.

In 1549, KingChakkraphat ordered the separation ofMueang Lopburi and Nakhon Nayok to createMueang Saraburi. The first record of a central district office is in Sao Hai at Tambon Sala Li Lao. The Mueang Saraburi office was moved to Tambon Pak Phriaw,Mueang Saraburi district in 1896. At the same time, the Sao Hai district office was moved to Tambon Suan Dokmai. Three years later it was moved again to Tambon Sao Hai near Chao Poo Shrine. In 1924 the owner of Sao Hai fresh market donated 12,800 m² of land about 500 m from the old location to build a new district office and police station for the district.

The name of the district means 'crying pillar', which originates from a local legend. At the time thecity pillar of Bangkok was built, the king asked for the most beautiful pillars from all over the country to be sent to the capital. The one sent from Saraburi was nearly perfect, but it arrived after a pillar had been chosen and thus was only made a secondary pillar. The pillar became very sad, floated back to Saraburi on theChao Phraya and Pa Sak Rivers, and sunk there. Later villagers heard the wails and erected the pillar there, which gave thetambon and thus the district its name. It is now in theChao Mae Takhian Tong Shrine within the Wat Sung Temple, near the district office of Sao Hai District.^[1]

Neighbouring districts are (from the northwest clockwise)Ban Mo,Phra Phutthabat,Chaloem Phra Kiat,Mueang Saraburi, andNong Saeng of Saraburi Province; andTha Ruea ofPhra Nakhon Si Ayutthaya province.

The main river of the district is thePa Sak River.

The district is divided into 12 sub-districts (tambon), which are further subdivided into 103 villages (muban). There are three townships (thesaban tambon): Sao Hai and Ban Yang each cover parts of the same-namedtambon, Suan Dok Mai coverstambon Suan Dok Mai.
