The Takamatsu Expressway (高松自動車道, Takamatsu Jidōsha-dō) is an expressway in the Shikoku region of Japan. The expressway is numbered E11.^[1]

The expressway is an important route connecting the greater Osaka area with Takamatsu, the capital of Kagawa Prefecture. Beyond Takamatsu, the route follows a westerly course parallel to the Seto Inland Sea to its terminus with Matsuyama Expressway and Kōchi Expressway in Shikokuchūō.

The speed limit is 80 km/h along the majority of the route, there are some 100 km/h sections between Naruto Junction and Tsuda-Higashi Interchange and Takamatsu-Nishi Interchange and Kawanoe Junction.

The first section of the Takamatsu Expressway to open was between Zentsuji and Mishima-Kawanoe interchanges on 16 December 1987. The final section of the expressway (9.1 km between Takamatsu-Chūō and Takamatsu-Nishi Interchanges) was opened on 30 March 2003. The 16.2 kilometres (10.1 mi) long Takamatsu-higashi Road was incorporated into the Takamatsu Expressway on 21 November 2017.^[2]

• IC - interchange, SIC - smart interchange, JCT - junction, SA - service area, PA - parking area, BS - bus stop, TN - tunnel, TB - toll gate

Due to open the expressway from Takamatsu towards Matsuyama, kilometer markers between Naruto Toll Gate and Takamatsu-Nishi Interchange show the distance from Naruto Toll Gate plus 100 (the marker at Naruto Toll Gate is 100.0 while the marker at Takamatsu-Nishi Interchange is 165.4). Therefore, the exit numbers continue from the sequence of the Takamatsu-Nishi Interchange, starting at 7.
