The Miss Idaho Teen USA competition is the pageant that selects the representative for the state of Idaho in the Miss Teen USA pageant. Idaho has only placed three times and as such is one of the least successful states at Miss Teen USA. Their first placement, and the state's only placement for the first twenty-five years of the competition, was in 1989 when Brandi Sherwood won the Miss Teen USA title becoming the 7th state that won the title for the first time. Sherwood went on to make history as the first Miss Teen USA to be crowned Miss USA.
