"Don't You Know (She Said Hello)" is a 1970 song by British band Butterscotch.

It was written and produced by the three group members, the songwriting team of Christian Arnold, David Martin, and Geoff Morrow.

The song became a hit in the British Isles, reaching number 17 in the UK[3] and number 18 in Ireland during the spring of the year.

Robin Carmody of Freaky Trigger has described it as a gem of 1970 British bubblegum pop, deeming it "as rosily innocent as 1955, impossible even a year later".

[1] The song was covered by Edison Lighthouse on their debut LP, Already.
