The B46 bus route constitutes a public transit corridor in Brooklyn, New York City. The route runs primarily along Utica Avenue north from the Kings Plaza shopping center through Eastern Brooklyn, with continued service west along Broadway to the Williamsburg Bridge Plaza Bus Terminal. The corridor was originally served by a streetcar line, known as the Utica and Reid Avenues Line, Utica−Reid Line, Reid−Utica Line, Reid Avenue Line, or Utica Avenue Line until 1951, when the line was replaced by bus service. The bus route is operated by MTA Regional Bus Operations under the New York City Transit brand.

The B46 consistently ranks among the top five busiest routes in New York City, and is the third busiest in Brooklyn after the B82 and B6, serving 13 million riders in 2017. Because of this, in 2009 the route was selected for conversion into bus rapid transit under Phase II of the city's Select Bus Service (SBS) program, implemented on July 3, 2016. The B46 was also notorious for high incidence of crime and fare evasion; in 2014, the magazine The New Yorker declared the route "the most dangerous bus route in the city", following several crimes such as the killing of a B46 bus driver in 2008.
