The Massachusetts Bay Transportation Authority (MBTA) operates two specially designated crosstown bus routes in the Boston, Massachusetts, United States area, called CT2 and CT3, and intended as limited-stop buses connecting major points. The two weekday-only routes largely parallel MBTA bus local routes, but with fewer stops to reduce travel times.

Three crosstown routes – CT1, CT2, and CT3 – were introduced in 1994.[1] Eight additional routes numbered CT4 through CT11 were proposed as part of an interim phase of the Urban Ring Project to provide circumferential service bypassing the crowded downtown subway stations, but were never put in service.[2] Route CT1 was merged with route 1 in 2019.[1] The Crosstown Routes will be phased out by 2028, according to current MBTA bus network redesign plans.
