TheBannan orBlue line (codeBL) is a metro line ofTaipei Metro inTaipei, Taiwan, with a total of 23 stations serving the districts ofNangang,Xinyi,Daan,Zhongshan,Wanhua,Banqiao andTucheng. The line's name is aportmanteau of Banqiao and Nangang.

The entire line runs underground. The excavation of tunnels using thecut-and-cover method resulted in large scale detouring of road traffic. Because of that, the line runs beneath existing roads and totals 28.3 km (17.6 mi).

Service on this line is divided into a full-length service fromTaipei Nangang Exhibition Center toDingpu, as well as a shorter service fromKunyang toFar Eastern Hospital.

Due toTaipei City Hall being at the centre of theTaipei 101 New Year's festivities, intervals between trains can be reduced to a minimum of 135 seconds, transporting up to 39,000 passengers per hour.^[1] This results in an average of about 27 trains per hour on the line during peak hours.
