"Father and Son" is a popular song written and performed by English singer-songwriter Cat Stevens (now known as Yusuf Islam) on his 1970 album Tea for the Tillerman. The song frames an exchange between a father not understanding a son's desire to break away and shape a new life, and the son who cannot really explain himself but knows that it is time for him to seek his own destiny.

Stevens sings in a deeper register for the father's lines, while using a higher one for those of the son. Additionally, there are backing vocals provided by Stevens' guitarist and friend Alun Davies beginning mid-song, singing an unusual chorus of simple words and sentences such as "No" and "Why must you go and make this decision alone?".

Cat Stevens originally wrote "Father and Son" as part of a proposed musical project starring British actor Nigel Hawthorne, called Revolussia, that was set during the Russian Revolution, and could also have become a film; the song was about a boy who wanted to join the revolution against the wishes of his conservative farmer father. The musical project faded away when Stevens contracted tuberculosis in 1969, he was close to death at the time of his admittance to the King Edward VII Hospital in Midhurst, West Sussex. After a year-long period of convalescence in the hospital and a collapsed lung (which might have been the result of too much fast living after first achieving fame) the project was shelved, but "Father and Son" remained, now in a broader context that reflected not just the societal conflict of Stevens' time, but also captured the impulses of older and younger generations in general.

"Father and Son" received substantial airplay on progressive rock and album-oriented rock radio formats, and played a key role in establishing Stevens as a new voice worthy of attention. In 1970 it was only put on the B-side of Stevens' single "Moon Shadow" (Island Records).
