Melissa Ann Hiatt (born October 16, 1963), better known by her ring name, Missy Hyatt, is an American retired professional wrestling valet, commentator, model and occasional professional wrestler. She is best known for her appearances with World Championship Wrestling from 1987 to 1994; she has also appeared with World Class Championship Wrestling, the Universal Wrestling Federation, the World Wrestling Federation (now WWE), Extreme Championship Wrestling, and Impact Wrestling.

Hyatt's professional wrestling career began in September 1985 when she was hired by the Dallas, Texas-based promotion World Class Championship Wrestling (WCCW) as a valet for her then-boyfriend, professional wrestler John Tatum. She became known for hitting her rivals with a "loaded" Gucci purse. She was embroiled in a feud with another valet in WCCW, Sunshine. This rivalry culminated into a mud-pit match at Texas Stadium in 1986.

In mid-1986, Hyatt and Tatum joined the Oklahoma-based Universal Wrestling Federation. Hyatt quickly began a lengthy feud with fellow valet Dark Journey that lasted until early-1987. Hyatt and Tatum joined Eddie Gilbert's stable, "Hot Stuff International", which was eventually renamed "Hot Stuff & Hyatt International". After a disagreement between Tatum and Gilbert, Hyatt aligned herself with Gilbert by hitting Tatum with her loaded purse during a bout between the two men.

While still under UWF contract, Hyatt was contacted about working for the World Wrestling Federation (WWF). Vince McMahon wanted Hyatt to replace Rowdy Roddy Piper and his segment, Piper's Pit, with a new segment called "Missy's Manor". "Missy's Manor" segments were taped on March 21 and 22, and April 23, 1987. Despite having big name stars on her segment such as "Macho Man" Randy Savage with Miss Elizabeth, The Honky Tonk Man and Harley Race, the show was considered a disappointment, and McMahon asked Hyatt to become a "Federette", one of the female attendants employed at television tapings to carry wrestlers' gowns and other pre-match apparel backstage at the start of bouts. She thought the role was beneath her, and she went back to the UWF.

In 1987, when the UWF was purchased by the National Wrestling Alliance's Jim Crockett Promotions, Hyatt and Gilbert briefly came along (Gilbert appeared in a six-man tag match as Starrcade (1987)) before moving to the Memphis, Tennessee-based Continental Wrestling Association where Hyatt accompanied Gilbert in his feud with Jerry Lawler. The couple later moved to the Knoxville, Tennessee-based Continental Championship Wrestling promotion where Hyatt revived the "Missy's Manor" interview segment. On one edition, Hyatt was held down by Samoans Sika and Kokina and forcibly kissed by their manager Alan Martin. After Gilbert declined to help Hyatt owing to important alliances with Martin, she began managing opponents to feud with Martin.

Hyatt returned to WCW with Gilbert when he decided to help Jimmy Garvin in his feud with Kevin Sullivan. She was used as a commentator, conducting her debut interview with Sir Oliver Humperdink on the December 31, 1988 edition of World Championship Wrestling on TBS.

In spring 1989, Hyatt became the manager of the Steiner Brothers, during which time she was billed as the girlfriend of Scott Steiner. After Robin Green was introduced as the girlfriend of Rick Steiner, Hyatt gave her a makeover on the August 26, 1989 episode of WCW Saturday Night. At Fall Brawl in September 1989, during a match between the Steiner Brothers and the Fabulous Freebirds, Scott Steiner was tripped by one of the women at ringside, with Hyatt and Green blaming one another. Later that month, it was revealed that Green had tripped Steiner, with Green turning on the Steiner Brothers and adopting the new name "Woman".

In 1990, Hyatt returned to her role as commentator and hosted WCW Main Event.
