Alfred Lennon (14 December 1912 – 1 April 1976), also known as Freddie Lennon, was an English seaman and singer who was best known as the father of musician John Lennon. Alfred spent many years in an orphanage with his sister, Edith, after his father died.

Lennon married Julia Stanley in 1938. John was their only child, but, as Alfred was away at sea during World War II, he did not see his son much during infancy. During this period Julia became pregnant with another man's child. Alfred offered to look after his wife, their child, and the expected baby, but Julia rejected the idea. Alfred had very little contact with his son until Beatlemania, when they met again, but later the pair had only intermittent contact with each other. Alfred died in Brighton, England, where he had lived since marrying Pauline Jones, with whom he had two sons.
