The Chikkō Line (築港線, Chikkō-sen) is a 1.5 km Japanese railway line in Nagoya, Aichi Prefecture, owned and operated by the private railway operator Nagoya Railroad (Meitetsu). At Meiden Chikkō, between the line's two stations, there is a connection to the freight-only Nagoya Rinkai Railway Tōchiku line.

The line was opened in 1924 by the Aichi Electric Railway, electrified at 1,500 V DC, to service the Nagoya Port.^[1] The line was double-tracked in 1939, but after being damaged by Typhoon Vera in 1959, the line was repaired as a single track.^{[citation needed]} Although the line used to handle many freight services, they ceased in 1984.^[2] A test line for testing maglev trains ran alongside the line between 1991 and 2004, but the line was removed after Linimo opened.^[3]

At the start of the March 16, 2024, timetable revision, the fleet of 5000 series four-car trains used on the line were replaced with 3100 series, 3150 series, and 9100 series two-car sets.^[4]

Regularly scheduled trains on the line run from 7:00 to 8:28 and 16:44 to 19:44 during weekdays with a frequency of 3~5 trains per hour. Two extra trains are scheduled in 6 a.m., one in 16:14, and three in 8 p.m. and 9 p.m. During weekends, trains run from 7:18 to 8:16 and 16:33 to 17:20 with a frequency of 1~3 trains per hour.
