Did Elton John win an Oscar award?

No. Sir Elton John's only Oscar was shared with Tim Rice for composing the Best Original Song of 1994. The award was for the song "Can You Feel the Love Tonight" from "The Lion King." John and Rice also were nominated that year for two other songs from the animated film: "Circle of Life" and "Hakuna Matata."

The Oscar-winning score for "The Lion King" was composed by Hans Zimmer.
