François-Joseph Boulanger was a Belgian veduta painter.

He was born as the son of French immigrants, François-Joseph Boulanger and Marie-Catherine de Puysseleir.

Boulanger was trained as a painter at the Koninklijke Academie voor Schone Kunsten in Ghent from 1841 to 1844 under Theodoor de Heuvel and in 1844 under Edouard De Vigne.

He debuted at the 1841 Salon in Ghent with a genre scene. He soon turned to the genre of veduta painting, with which he was henceforth represented in many prominent salons in Belgium.

He showed his works at the art exhibitions in Antwerp in 1849, 1852, 1855, 1858 and 1861, and in Brussels in 1850 and 1866.

In the last years of his life, he fell victim to alcoholism and died in a mental hospital.

His younger brother Jules Joseph Boulanger (1822-1868) was also a painter.
