The Strait of Gibraltar tunnel (Spanish: Túnel del estrecho de Gibraltar, Arabic: نفق جبل طارق) is a proposed rail tunnel spanning the Strait of Gibraltar that would connect Europe and Africa. If built, the tunnel would possibly be the longest railway tunnel in the world, surpassing the Gotthard Base Tunnel and the under-construction Mont d'Ambin Base Tunnel, as well as the longest undersea tunnel, surpassing the Seikan Tunnel.
Since the completion of Morocco's first national high-speed rail line from Casablanca to Tangiers in 2018, there has been renewed interest in a tunnel that would connect the line to Spain's own high-speed network, which uses the same gauge and electrification as the northern section of Morocco's Casablanca-Tangier high-speed line.
