Miss Arkansas USA, previously known as Miss Arkansas Universe, is the beauty pageant that selects the representative for the state of Arkansas in the Miss USA pageant, and the name of the title held by that winner. The pageant is directed by Vanbros and Associates.

Arkansas's most successful placement was in 1982, when Terri Utley was crowned Miss USA. The most recent placement was Mackenzie Hinderberger in 2023 who placed in the Top 20. Eight Miss Arkansas USA titleholders were former Miss Arkansas Teen USA titleholders who competed at Miss Teen USA. The longest reigning titleholder was Haley Rose Pontius in 2020, having held the title for 18 months, while the shortest titleholder was Stephanie Barber in 2021, having held the title for 10 months and 18 days.

The state pageant was directed by Premier Pageants from 2002 to 2007 before becoming part of the Vanbros organization, headquartered in Lenexa, Kansas. In 2018, Vanbros chose Fort Smith, Arkansas as the new host city of the pageant. Other host cities for the pageant have included Bentonville, Little Rock, Magnolia, and West Memphis.

The current Miss Arkansas USA is Olivia Halsey of Jonesboro who was crowned on April 13, 2025 at The Center for the Arts in Russellville. She represented Arkansas at Miss USA 2025.

Arkansas holds a record of 16 placements at Miss USA.
