"It's Gonna Work Out Fine" is a song written by Rose Marie McCoy and Sylvia McKinney, and released as a single by Ike & Tina Turner in 1961. It is noted for being their first Grammy nominated hit and their second million-selling hit after "A Fool in Love".

The song was recorded a year after Ike and Tina Turner broke through with their blues-oriented soul number, "A Fool in Love", which accidentally formed the duo after Sue Records president Juggy Murray refused to erase Bullock's raspy delivery from the record. Insisting on equal billing, Ike Turner included himself in the billing and renamed Anna "Little Ann" Bullock to Tina Turner, adding his last name, though the couple were not married at the time.

While their follow-up single, "I'm Jealous", was a monumental failure, the couple had a sizeable R&B hit with another Ike Turner composition, "I Idolize You". Working with Ike and Tina on the track was another popular duo, Mickey & Sylvia, who reportedly supported the recording by adding their guitar work and backing vocals to the track. Mickey Baker insisted that Ike Turner was not part of the original recording, stating that he was coached to be "Ike" while delivering spoken responses to Tina's lyrics. Ike Turner claimed he was in on the recording and that the guitar work was his.

Rose Marie McCoy stated, "I wrote the song, but I heard that Tina didn't really care for it. Anyway, at the time, Sylvia (McKinney) told me I had to "hear this girl sing it." When Ike and Tina came to New York, I went up to the Apollo to see them. Ike called Tina in the room. He said "Sing that song." She didn't say a word, but she sang. She sang like her life depended on it. I told Sylvia, if it sounds that good now, I can't wait to hear it with the music behind it."

Released in the summer of 1961 on Sue Records, the song became the duo's second crossover hit, reaching number 14 on the Billboard Hot 100 and repeating the same spot of "A Fool in Love" on the R&B chart at number two. Much like "A Fool in Love", the song became an early highlight of Ike & Tina's live shows as the duo's band transformed from The Kings of Rhythm in which Tina was the lead vocalist and sole dancer into The Ike & Tina Turner Revue, by 1962. It also resulted in the group's first Grammy nomination for Best Rock & Roll Vocal Performance By a Duo or Group.
