"Who You'd Be Today" is a song written by Aimee Mayo and Bill Luther and recorded by American country music singer Kenny Chesney.

It starts off with two teenage boys in a basketball practice, and then cuts to Chesney's performance, and subjects related to the song's storyline.

A high-school couple is seen talking together, and flashbacks are seen, implying that the woman was killed in a car crash.

As the boys run up the basketball court, one of them disappears, revealing the other one to be playing alone and reflecting on the past with his friend.

The music video reached number 1 on CMT's Top Twenty Countdown for the week of December 15, 2005.
