John Gidding (born January 7, 1977) is a Turkish-American designer, television personality, and former fashion model.

He was voted one of "Yale's 50 Most Beautiful People" in 1999 by Rumpus Magazine, one of "Boston's 50 Most Eligible Bachelors" by The Improper Bostonian in 2002, one of "Atlanta's 50 Most Beautiful People" by Jezebel Magazine and as one of Atlanta Homes and Lifestyles's "Emerging Talent: Twenty Under 40" in 2008.

Gidding's start in television was with the ABC Family TV show Knock First, where he and three other designers took turns making over teenagers' bedrooms.

Designed to Sell (Giddings' previous show from 2006 to 2011) was cancelled in early 2011 by HGTV, and Knock First is still running in syndication internationally.

He is best known as the designer on Curb Appeal: The Block[1] where his team spent $20,000 on improvements to the exterior and landscaping of chosen homeowners.
