Transport in Mexico City consists of a variety modes, including the roads, the Mexico City Metro, extensive bus and bus rapid transit systems (the Metrobús, RTP, and the trolleybus), as well as the Xochimilco Light Rail and cable cars. The city is serviced by the Benito Juárez International Airport which is supported by the Toluca and Zumpango airports, both in the neighboring State of Mexico. Additionally, like other cities around the world, Mexico City has public taxis, public buses and share taxis and rickshaws. Trajineras, gondola-like boats, service the Xochimilco Lake area. Previously, the city used to operate streetcars. The Greater Mexico City area has additional routes that provide services to the city, including the Tren Suburbano commuter railway, the Mexibús BRT network, and the Mexicable aerial lift system. The transport services are operated by public or private entities but all of them are regulated in the city by the Secretaría de Movilidad (SEMOVI; Secretary of Mobility).

The systems are also considered by the users as inefficient, ineffective, and face problems such as the lack of regulation and official supervision.

As each line opened, the 'pesero' minibuses were removed from each route, in order to reduce pollution and commute times. As of mid-2017, there were 568 Metrobús buses. In late 2016 they transported an average of 1.1 million passengers daily. Mexibús provides 4 bus rapid transit lines connecting Metro Ciudad Azteca and Metro Pantitlán with Cuautitlán, Ecatepec and other suburban areas in the State of Mexico. Public buses The peseros are typically half-length passenger buses (known as microbús) that sit 22 passengers and stand up to 28. , the approximately 28,000 peseros carried up to 60 percent of the city's passengers.
