Line 12 of the Dalian Metro (Chinese: 大连地铁12号线; pinyin: Dàlián Dìtiě Shí'èr Hào Xiàn) is a rapid transit line running in northern Dalian.

The line connects central Dalian with Lüshunkou over 40.38 kilometres (25.09 mi)[1] with 8 stations from east to west.

Similar to Line 3, all the stations have side platforms with tracks in the platform area have no ballast (gravel); however, tracks outside the station are on ballast.

Also all stations are covered by a combination of transparent corrugated sheets and a concrete roof.

[2] In October 2017, most station names were re-translated from Pinyin into conventional English.
