Memoirs of a Police Sergeant (Portuguese: Memórias de um sargento de milícias) is a satirical novel written by the Brazilian author Manuel Antônio de Almeida. It was first published in 1852. The book is full of picturesque descriptions of Rio de Janeiro's life in the early 19th century, including popular feasts and holidays. The book is considered to be an outstanding work in the Brazilian Literature, because of its almost grotesque humor against some Brazilian institutions, like the Army, the Church and is considered, besides a literary masterpiece, an important source of Brazilian history.
