"Do You Believe Me Now" is a song written by Tim Johnson, Joe West and Dave Pahanish, and recorded by American country music singer Jimmy Wayne. It was released in March 2008 as the first single and title track from his album Do You Believe Me Now, which was released on August 26, 2008. His first Top 40 single on the country charts since "Paper Angels" in late 2004-early 2005, it is the third single of his career to reach the Top Ten on the Billboard Hot Country Songs chart, as well as his first number one.

The song is a mid-tempo centralizing on the male narrator, who is speaking to a former lover. In the first verse, he tells her that he "didn't like the way" that another man was looking at her, to which she responds by saying that it was only the narrator's imagination. In the chorus, the narrator then asks the female if she believes him now, as it turns out his suspicions were correct and she is now with that other man. The second verse then finds the narrator feeling sorry for himself because he gave the other male a chance to take her away from him. In the bridge, the narrator is unable to find solace in this knowledge, as he says, "what's the use in being right when I'm the lonely one tonight?"

According to Country Weekly, songwriter Tim Johnson was encouraged to write the song after his friend was with another girl. He got together with friends Dave Pahanish and Joe West to write the song, and it was finished after about a month. They played the song for Wayne, who liked the song and decided to record it.

The music video for this song begins with Wayne filming a girl's birthday party. It then zooms out to reveal Wayne watching the party on TV himself. The camera follows the girl around and reveals that it is his lover when they kiss. The camera then keeps filming as a guy walks into the scene and starts talking to her. Later the guy again approaches her and makes her laugh, right as Wayne turns the camera on them. He puts the camera down in disappointment. Each time the girl and the other guy are in a scene, Wayne pauses the film and watches in silence. Scenes also feature him sitting on a stairwell, playing guitar, and standing up against a large window.
