The Cádiz Bay tram-train, popularly known as Trambahía, is a tram-train/light rail system in the Spanish city of Cádiz and the surrounding area. The 24 km (14.9 mi) system opened on 26 October 2022.

It is the fourth metropolitan light rail system to be built in Andalusia, after Seville Metro (2009), Málaga Metro (2014) and Granada Metro (2017). It is also the fourth by number of passengers carried - over 2.1 million in 2024.
