Nikki Cleary (born May 11, 1988 as Brittney Nicole Cleary) is a pop-rock singer.

Cleary first hit the pop market with the catchy song "I.M. Me" while still using her given name. Her debut album, Everything I Wished For, was released independently under the Free Falls record label. The album hit #45 on Billboard's Top Independent Albums chart. When Cleary signed with Jive Records in the summer of 2002, they asked to change her name because they already had a Britney on their roster. Her self-titled album, Nikki Cleary was released in the summer of 2003 with the hit single "1-2-3" making noise on Billboard's Radio Disney Top 30.

She was featured on a Nickelodeon Kids' Choice Awards record in 2003. Once performed on Nickelodeon's "All That." Nikki Cleary also did a version of "Summertime Guys". Nikki contributed to the Mean Girls motion picture soundtrack with the song "Hated". The song wasn't put on her own albums because it had words like "bitch" and "I wish you would choke and die" and it would disrupt her squeaky clean image.
