Manuel Summers Rivero (26 March 1935 – 12 June 1993) was a Spanish film director, screenwriter and actor.

His father, Francisco Summers e Isern (1902–1990), was a Francoist lawyer who served as civil governor of the provinces of Huelva in 1952–1956 and of Granada in 1956–1960.

Summers' earlier films, such as Del rosa al amarillo (1963) and La niña de luto (1964), have been described as bittersweet comedies with satirical undertones, and can be situated as examples of the "new Spanish cinema" of the 1960s.

Problems with censorship and lack of popular success led Summers to gradually abandon the critical features of his earlier works as a director, and he went on to direct lighter comedies from the late 1960s.

In total, Summers would direct twenty feature films during his career.
