New Brunswick is one of Canada's three Maritime provinces (together with Prince Edward Island and Nova Scotia) and is the only constitutionally bilingual (English–French) province. The principal cities are Fredericton, the capital, Greater Moncton, currently the largest metropolitan (CMA) area and the most populous city, and the port city of Saint John, which was the first incorporated city in Canada and largest in the province for 231 years until 2016. 

In the Canada 2016 Census, Statistics Canada estimated the provincial population to have been 747,101, down very slightly from 751,171 in 2011, on an area of almost 73,000 km. The majority of the population is English-speaking of Anglo and Celtic heritage, but there is also a large Francophone minority (31%), chiefly of Acadian origin. It was created as a result of the partitioning of the British colony of Nova Scotia in 1784 with the capital in Saint John before being moved up river. The name 'New Brunswick' was chosen by King George III despite local recommendations for the name to be 'New Ireland'. The provincial flag features a ship superimposed on a yellow background with a yellow "lion passant guardant" on red pennon above it. 

The province is named after the city of Braunschweig ("" in English and Low German) in the former Duchy of Brunswick-Lüneburg, what is now Lower Saxony in northern Germany. The then-colony was named in 1784 to honour the reigning British monarch, George III, who was concurrently Duke and prince-elector of Brunswick-Lüneburg ("Hanover") in the Holy Roman Empire.
