"Knock, Knock Who's There?" is a 1970 song by Welsh singer Mary Hopkin. Written and composed by John Carter and Geoff Stephens it was the United Kingdom's entry at the Eurovision Song Contest 1970 where it came 2nd. The single version was produced by Mickie Most and reached No.2 in the UK Charts.

On 7 March 1970, Mary Hopkin sang six songs at the UK National Final, A Song for Europe, which was aired on the television series It's Cliff Richard!. Hopkin was chosen by the BBC to be the United Kingdom's representative for that year, and the winner of a postal vote would determine which of the six songs would progress with her to the finals in Amsterdam. "Knock, Knock Who's There?", the sixth and final song performed that evening, won the postal vote with over 120,000 supporters.

At Amsterdam, the song was performed seventh on the night, after France's Guy Bonnet with "Marie-Blanche", and before Luxembourg's David Alexandre Winter with "Je suis tombé du ciel." At the end of judging that evening, "Knock, Knock Who's There?" took the second-place slot with 26 points after Ireland's "All Kinds of Everything", performed by Dana. The UK received points from nine out of a possible eleven voting juries.

The singer expresses a long-held optimism at the prospect of love finally finding her. At the exact point that said optimism has faded, and she has resigned herself to not finding love and companionship, she hears a "knock, knock," which signifies love finally becoming attainable for her. Excited, she beckons love to "come inside" and into her life.
