Songkhla (สงขลา, sǒŋ.khlǎː), also known as Singgora or Singora (Pattani Malay: ซิงกอรอ, Singoro), is a city (thesaban nakhon) in Songkhla Province of southern Thailand, near the border with Malaysia. Songkhla lies south of Bangkok and as of 2020 had a population of 61,758.
Despite being smaller than the neighboring city Hat Yai, Songkhla is the capital of Songkhla Province as well as the Mueang Songkhla District (Songkhla town district). Together with Hat Yai, Songkhla is part of the Greater Hat Yai-Songkhla Metropolitan Area (a conurbation with a population of around 800,000), the third largest metropolitan area in Thailand.
At the opening of Songkhla Lake to the Gulf of Thailand, Songkhla is a fishing town and also an important harbour. It is the major seaport on the east side of the Isthmus of Kra.
The name Songkhla is the Thai variant of "Singgora" (Jawi: سيڠڬورا); its original name means 'the city of lions' in Malay (not to be confused with Singapura). This refers to a lion-shaped mountain near the city of Songkhla. Archaeological excavations on the isthmus between Lake Songkhla and the sea reveal that in the 10th through the 14th century, this was a major urbanized area, and a center of international maritime trade, in particular with Quanzhou in China. The long Sanskrit name of the state that existed there has been lost; its short Sanskrit name was Singhapura ('Lion City') (not to be confused with Singapura), a city state. The short vernacular name was Satingpra, coming from the Mon-Khmer sting/steng/stang (meaning 'river') and the Sanskrit pura ('city').
The ruins of the ancient port city of Satingpra are just few kilometers north of Songkhla. It was one of the most important trading centers of the Tambralinga Kingdom. Archaeological digs and investigations conducted toward the end of the 20th century testify the existence of a fortified citadel protected by a moat and a quadrangular surrounding wall made of brick. A sophisticated system of canals connected the sea to the Songkhla Lake permitting the circulations of ships.
