The Miss Delaware Teen USA competition is the pageant that selects the representative for the state of Delaware in the Miss Teen USA pageant. It is formerly directed by Crown Productions from 2003 to 2010, then to D&D Productions from 2011 to 2018. CW Productions became the new directors for the pageant from 2019.^[1]

Myah Rosa-Scott of New Castle was crowned Miss Delaware Teen USA 2019 on November 18, 2018 at Chase Center on the Riverfront in Wilmington. She represented Delaware for the title of Miss Teen USA 2019 on April 28, 2019 in Reno, Nevada.

In terms of number of placements and awards, Delaware is one of the least successful states at Miss Teen USA. However, Ashley Coleman broke the mold to win the Miss Teen USA crown in 1999. Miss Delaware Teen USA 2000, Carrie Aiken, and 2001, Christie Aiken, are sisters. Miss Delaware Teen USA 1997, Cheryl Crowe, was the first Delaware teen to cross over to the Miss Delaware USA title. Since Cheryl, Kelsey Miller (2009), Mia Jones (2014) and Sierra Wright (2015) went on to win the Miss Delaware USA title, in 2014, 2017 and 2018 respectively. Miss Delaware Teen USA 2011, Amanda Debus, was the first, and so far only, Delaware teen to cross over from the Miss Delaware's Outstanding Teen title, she is also the only successful MAO/MUO crossover in Delaware. Amanda Debus is the first USA titleholder to win Miss Delaware in the Miss America system.

On February 26, 2013, Melissa King resigned her crown when confronted with a pornographic video ^[2][3][4]

The former Miss Delaware Teen USA was paid $1,500 for the porn shoot.^[5] The video producers said that King contacted them to shoot the video and was willing to film more scenes.^[5]

Hailey Lawler, the runner-up, replaced her.^[6]
