Sabarimala International Greenfield Airport (IATA: none, ICAO: none), is a proposed greenfield international airport, that will cater to the cities of Kottayam and Pathanamthitta, as well as the pilgrimage site of Sabarimala in Pathanamthitta district. The airport will be built in between the towns of Erumeli South and Manimala. Pathanamthitta is the nearest major urban center to the proposed site. The proposed site is 53.9 km away from Sabarimala temple, 9.2 km away from Kanjirappally town and 9 km away from Ranni town. The site is located at about 40 km from the city of Kottayam. The site is spread over 2,570 acres (10.4 km) of area. It is 136 km from the state capital, Thiruvananthapuram, and 113 km from Kochi. Upon commissioning, this will be the fifth international airport in Kerala, giving the state the distinction of having the most international airports in India.

The Sabarimala temple, situated on the Western Ghats in Kerala's Pathanamthitta district and is one of India's holiest shrines, which attracts nearly around 50 million visitors each season. As of December 2019, an average of 75,000 pilgrims visit Sabarimala on a daily basis ever since the beginning of the annual pilgrim season in mid-November. Presently, the only way to reach the hill shrine is by road. The increase in the number of pilgrims visiting the temple had prompted the government to look at an airport as an option to reduce traffic congestion during the pilgrimage season. In view of this, in February 2017, the Government of Kerala gave in-principle approval to construct the airport, and the Kerala State Industrial Development Corporation (KSIDC) was asked to conduct a feasibility study.

KSIDC had issued global tenders for the feasibility study of the project. The tender was won by the American consultancy firm, Louis Berger Group. Louis Berger submitted a techno-economic feasibility study and environmental impact assessment of the proposed greenfield airport in December 2018. However, the consultancy did not conduct the environment impact assessment (EIA) as the state had not taken a final decision on the project including that of land acquisition. In 2019, the state government constituted a search committee to select a special officer for the project, who would be given the task of coordinating with the consultancy in acquiring environment impact clearances and for the union civil aviation ministry’s approval for the project. In December 2019, the state government appointed V. Thulasidas, the managing director of Kannur International Airport Ltd. (KIAL) as the special officer for the project. In April 2023, after a long delayed and complicated process as mentioned above, the project got approval from the Ministry of Civil Aviation, and preparation of the project's Detailed Project Report (DPR) is expected to begin within a month.

The site for the proposed airport is nearby the Cheruvally Estate, which was formerly the site of a rubber plantation. Initially, the estate belonged to Harrison Plantations and later by the RPG Goenka group. Gospel for Asia, a Christian missionary organization under Believers Eastern Church took it over from the Goenka group. The ownership of the property was disputed in 2017 before the High Court of Kerala claiming that the Estate was government land. A 2018 High Court order affirmed the church's ownership of the estate.
