The TH Liner (THライナー) is a limited-stop "Home Liner"-style service to and from Kuki Station in Saitama on the Tobu Isesaki Line operated by the private railway operator Tobu Railway in Japan since June 2020.

TH Liner services are operated by a fleet of 70090 series 7-car electric multiple units (EMUs).

Starting at Kasumigaseki, passengers may get on and off at any of the serviced Hibiya line stations until the terminus at Ebisu.

For the evening "down" services, passengers can only get on the train at the Hibiya Line stations starting at Kasumigaseki.

Later on 19 December, additional details were announced such as the name of the service, stopping pattern, and schedule.
