The Nagoya Municipal Subway 3000 series (名古屋市交通局3000形^?) is a rapid transit electric multiple unit operated by the Transportation Bureau City of Nagoya on the Nagoya Subway Tsurumai Line in Japan since 1977.

Originally delivered as 4-car sets, the trainsets were reformed into 6-car sets from 1993 as shown below with former cab cars inserted within the formations. Two surplus 3000 series cars were inserted into a later 3050 series set.
