A regional jet (rg ) is a jet airliner and a regional airliner with fewer than 100 seats. The first one was the Sud-Aviation Caravelle in 1959, followed by the widespread Yakovlev Yak-40, Fokker F-28 and BAe 146. The 1990s saw the emergence of the most widespread Canadair Regional Jet and its Embraer Regional Jet counterpart, then the larger Embraer E-Jet and multiple competing projects. In the US, they are limited in size by scope clauses.

In the US, they are limited in size by scope clauses. The market was consolidated as Bombardier Aviation sold its airliner programs between 2017 and 2019, leaving Embraer as the sole large independant regional jet manufacturer, while emerging players try to push competitors: the Mitsubishi Regional Jet, Sukhoi Superjet 100, Comac ARJ21 and Antonov An-148.
