The European route E751, or E751, as defined by the Declaration on the Construction of Main International Traffic Arteries of 1975, and subsequent documents which amended the treaty, is an east–west Class-B branching European road route. Originating in Rijeka, Croatia, where it diverges from European route E61 before passing through the Kanfanar interchange, the route connects Pula, Rovinj, Poreč and Umag in Croatia with Koper in Slovenia. The route provides a high-performance road link in Istria and Slovenian Littoral. Unlike most routes, the E751 centers on the Kanfanar interchange and has three arms, each extending to Rijeka, Pula and Koper. The total length of the route, including all the route arms, is 160 km (99 mi).

The E751 mostly consists of motorways, but considerable sections are either expressways or two-lane roads with at-grade intersections. All motorway sections of the E751 are tolled, using the electronic toll collection (ETC) and ticket systems. Since the 1980s, the E751 has gradually been upgraded from a regular two-lane road to motorway standards, and further upgrades are still being carried out or planned in some areas, particularly in the Rijeka–Kanfanar section and in the section located in Slovenia. The bulk of the E751 consists of the Istrian Y roads operated by BINA Istra. The part of the route in Slovenia is managed by the Slovenian Roads Agency, part of the Government of Slovenia.

The E751 is considered to be of great importance for the economy and tourist industry of the region, as it links many resorts to motorway systems in Slovenia and Croatia, providing a significant access route for thousands of motoring tourists. Furthermore, two endpoints of the E751 are located in the vicinity of the two major Adriatic seaports of Rijeka and Koper.
