Nishi-Nagoya Thermal Power Station (西名古屋火力発電所, Nishi-Nagoya Karyoku Hatsudensho) is an LNG-fired thermal power station operated by JERA in the village of Tobishima, Aichi, Japan. The facility is located on reclaimed land at the head of Mikawa Bay.

The Nishi-Nagoya Thermal Power Station began operations in 1970 as an oil-fired power plant operated by Chubu Electric. Unit 1 through unit 6 were constructed between 1970 and 1975. On September 14, 2010, Chubu Electric announced a renewal plan to replace the aging existing facilities with a high-efficiency natural gas-fired combined cycle power generation system.

Construction began on Units 7-1 and 7-2 on January 30, 2014. Unit 7-1 came on-line on September 29, 2017, and Unit 7-2 on March 30, 2018. Both Unit 7-1 and 7-2 use a Toshiba exhaust heat recovery multi-shaft 1,600 °C class combined cycle power generation system (MACCII) in which three generators are connected to three gas turbines and one steam turbine. In order to transport the natural gas used at this power plant, a submarine tunnel with a length of 4.6 km extending from the Chita Daini Thermal Power Station was constructed. In March 2018, Guinness World Records certified the Nishi-Nagoya Thermal Power Station Unit 7-1 as the world's most efficient combined cycle power generation facility.

In April 2019, the operations of Chubu Electric Power were transferred to JERA, a joint venture between Chubu Electric and TEPCO Fuel & Power, Inc, a subsidiary of Tokyo Electric Power Company.
