The Toyohashi Railroad Atsumi Line (豊橋鉄道渥美線, Toyohashi Tetsudō Atsumi-sen^?) is a railway line in eastern Aichi Prefecture, Japan, operated by the private railway operator Toyohashi Railroad ("Toyotetsu"). The line runs from the centre of Toyohashi, traversing the centre of the Atsumi Peninsula, a largely rural district noted also for its hot spring resorts and marine sports as part of Mikawa Wan Quasi-National Park. The line is entirely within the cities of Toyohashi and Tahara.

The northern terminal station for the Atsumi Line is located at Shin-Toyohashi Station. All trains run to the southern terminus at Mikawa Tahara Station at approximately 15 minute intervals. There are no express trains on the line.

As of April 2015^[update], the line is operated using a fleet of ten three-car 1800 series electric multiple unit (EMU) trains. These trains were modified from former Tokyu 7200 series EMUs. All trains are configured for One-man operation.

Since 2013, the trains are each painted a different colour and carry the names of flowers, as follows.

The privately owned Atsumi Electric Railway (渥美電鉄, Atsumi Dentetsu^?) began operations on January 22, 1924 between Takashi and Toshima, electrified at 600 V DC. The line was extended to Kambe in March and to Mikawa Tahara by June 10 of the same year. In the opposite direction, the line was extended to Shin-Toyohashi by May 1925. On April 10, 1926, the now-defunct section of track from Mikawa Tahara to Kurokawahara was completed. Construction of a proposed extension to Fukue commenced in 1940, but was later abandoned due to material shortages in World War II.
