"You're the Best Thing That Ever Happened To Me" — also known simply as "Best Thing That Ever Happened To Me" — is a song written by Jim Weatherly, and enjoyed two runs of popularity, each by an artist in a different genre.

Weatherly told Tom Roland in The Billboard Book of Number One Country Hits that he wrote the song in 1971 and let his father-in-law first record it as a Christmas present for the latter's wife. "I thought it was really strange that nobody'd written a song with that title — possibly somebody had, but I'd never heard it — so I just sat down and let this stream of consciousness happen. I basically wrote it in a very short period of time, probably 30 minutes or an hour."

The song's first run of popularity, as "You're the Best Thing That Ever Happened to Me," came in 1973. That's when country music singer Ray Price took the song to No. 1 on the Billboard magazine Hot Country Singles chart on October 6, 1973.

For that version, it represented a last and a first. The "last" was Price's seventh and most recent No. 1 single, in a string dating back to his 1956 hit "Crazy Arms." The "first": It was the No. 1 single on the debut program of "American Country Countdown," which used the Billboard chart in its programming. Although it fell short of the top 40 in his native United States, the song was an easy listening hit in Canada, his third such hit there.

In the early- to mid-1970s, Gladys Knight & the Pips recorded several of Weatherly's songs, and in 1974, they dipped into his catalog once again with their rendition of the song. Their version, titled "Best Thing That Ever Happened to Me," reached No. 3 on the Billboard Hot 100 that spring and topped the Hot Soul Singles for two weeks. The single was certified gold by the RIAA for sales of one million copies. It also reached the top 10 in the United Kingdom.

Also, earlier in 1974,the same year that Gladys Knight & The Pips recorded the song, The Persuaders also recorded a version, taken from their album of the same name Their version was quieter,less brassy, and more introspective than The Pips' version It was released before the Pips' version as ATCO single # 45-6596
