The Q20A and Q20B (collectively referred to as Q20A/B or Q20) and Q44 bus routes constitute the Main Street Line, a public transit line in Queens, New York City, running primarily along Main Street between two major bus-subway hubs in the neighborhoods of Jamaica and Flushing. The Q20A/B terminates in College Point at the north end of Queens. The Q44 continues north into the borough of the Bronx, terminating in the West Farms neighborhood near the Bronx Zoo. The Q44 is one of two Queens bus routes to operate between the two boroughs (along with the Q50). The Q20A/B will be absorbed into the Q20 on June 29, 2025.

The Q44 and Q20 were originally operated by the North Shore Bus Company from the 1930s to 1947; they are now operated by MTA Regional Bus Operations under the New York City Transit brand. In June 1999, the Q44 began limited stop service in Queens, with the Q20 split into two branches to provide local service. On November 29, 2015, the Q44 was converted into a Select Bus Service (SBS) route.
