Kahdeksas veljes (The Eighth Brother) is a 1971 Finnish film directed by Spede Pasanen. It was Pasanen's first completely independent work as a screenwriter and director. The film attracted 176,175 viewers to theaters.

Despite the title, the plot bears no connection to Aleksis Kivi's Seven Brothers, nor is it a sequel to the earlier Spede production, Noin 7 veljestä. The only reference to the title comes in the opening credits, where it is jokingly claimed that there was, in fact, an eighth brother, whom Kivi omitted because he had been bribed.
