Mahir Çağrı (, born 1962) is a Turkish individual who became an Internet celebrity in 1999. His picture-laden personal homepage, which exclaimed, in broken English, his love of the accordion, travel, and women, was visited by millions and spawned numerous fansites and parodies, one of which was featured on Fox's MadTV (season 5, episode 20). He was also repeatedly parodied in 1999 on episodes of the Late Show with David Letterman, wearing red Speedos and playing ping-pong. Çağrı was ranked #2 in CNET's Top 10 Web fads. The site was also included in PC World's "The 25 Worst Web Sites" list. Çağrı claimed in various interviews that his personal webpage was hacked, with additions such as "I like sex" embedded into his webpage. The site was originally hosted on the now defunct XOOM web hosting service which advertised Çağrı on its front page during the mania. Çağrı was used in British TV advertising for smartgroups.com by St. Luke's advertising agency.

Similarities to Borat

Çağrı has stated that Sacha Baron Cohen's character Borat was based on him, and is therefore owed some sort of royalties for use of his likeness.
