A Cotral bus

Cotral SpA (In Italian: Compagnia Trasporti Lazio or Lazio Transport Company) is a limited company which runs suburban and inter-urban public transport services in the Lazio region of Italy.

Founded in 1976 through the merger of regional public transport operators in Lazio, Cotral inherited from one of these, STEFER, the management of the Rome metro, the concession railways Rome-Lido, Rome-Civita Castellana-Viterbo, and Rome-Fiuggi-Frosinone, as well as the tramways of the Castelli Romani.

In 2000, the management of the metro-rail system was separated from the original company with the creation of Met.Ro. (later merged into ATAC), leaving Cotral with the sole management of the interurban and suburban bus network in Lazio. Together with ATAC and Trenitalia, it participates in the Metrebus integrated fare system.

In the period 2018-2022, the Municipality of Rome initiated and completed the transfer of the Rome-Viterbo and Rome-Lido lines (now renamed "Metromare") to the Lazio Region, which entrusted Cotral with passenger services and Astral with infrastructure management.

Connecting all the municipalities in Lazio - excluding the island municipalities of Ponza and Ventotene - and with a total of over 8,000 daily trips, Cotral is estimated to transport more than 70 million passengers each year.
