"Mr. Know It All" is a song recorded by American pop recording artist Kelly Clarkson. It was written by Brian Kennedy, Ester Dean, Brett James, and Dante Jones, with the production handled by Kennedy, Dean, and Jones. Clarkson described the song as a "vocally raw record" and stated that she and her producers strove to record her voice as it is heard at live performances, using as little auto-tune processing as possible. It was released by RCA Records as the lead single from her fifth studio album, Stronger on September 5, 2011. "Mr. Know It All" is a midtempo song with R&B influences, with its lyrical content dealing with the themes of heartbreak, and relationships with wisenheimers.

Internationally, the song topped the charts in Australia and in South Korea, and has attained a top-ten position in New Zealand, Poland, Flanders (Belgium), and the United Kingdom. It also became a crossover hit to the Billboard Hot Country Songs chart, becoming her first solo single to enter the country chart after 9 years since "A Moment Like This" (2002), prompting RCA to release a country version produced by Dann Huff in 2012. The song's accompanying music video was directed by Justin Francis and features a "wall of doubt" background in which derogatory headlines about Clarkson are posted.
