Kienapple v R, [1975] 1 S.C.R. 729 is a leading decision of the Supreme Court of Canada that established the rule against multiple convictions known as the Kienapple principle. Justice Bora Laskin, for the court, held that an accused cannot be convicted of two offences where they both arise out of substantially the same facts.

John Edward Kienapple was charged with rape and unlawful sexual intercourse with a female under 14 years of age. At trial he was convicted on both charges. On appeal to the Supreme Court his conviction for unlawful sexual intercourse was overturned.
