Pathanamthitta District (IPA: [pɐt̪ːɐnɐn̪d̪iʈːɐ]), is one of the 14 districts in the Indian state of Kerala. The district headquarters is in the town of Pathanamthitta. There are four municipalities in Pathanamthitta: Adoor, Pandalam, Pathanamthitta and Thiruvalla.

According to the 2011 Census of India, the population was 1,197,412, making it the third least populous district in Kerala (out of 14), after Wayanad and Idukki. Pathanamthitta has been declared the first polio-free district in India. The district is 10.03% urbanised. Pathanamthitta is one of the richest districts in India with just 1.17% poverty as of 2013, which places the district among the top 5 districts in India with least poverty.

The district's name is a combination of two Malayalam words, pathanam and thitta, which together mean 'array of houses on the river side'. The district capital is located on the banks of the river Achankovil.

It is presumed that the regions that form the district were formerly under the rule of Pandalam, which had connections with the Pandya kingdom. When Pandalam was added to the princely state of Travancore in 1820, the region came under Travancore administration. The Nedumpuram Palace near Thiruvalla belongs to Valluvanad Royal family. Pathanamthitta district, along with most parts of Alappuzha district, was part of the Quilon division of the Travancore Kingdom until 1949.

The district was formed on 1 November 1982 as a reward to K. K. Nair, who was the then Pathanamthitta MLA, by K. Karunakaran. The formation was done by incorporating various portions of the erstwhile Kollam, Alappuzha and Idukki districts. While the taluks Adoor, Konni, Pathanamthitta, Kozhencherry and Ranni were taken from Kollam district; Pandalam, Kulanada, Aranmula, Kumbanad, Parumala, Thiruvalla and Mallapally were taken from Alappuzha district; and Sabarimala from Idukki district.
