Donna Adamo is an American retired professional wrestling valet and professional wrestler, better known by her ring name, Elektra. She is best known for her appearances with the Philadelphia, Pennsylvania-based promotion Extreme Championship Wrestling from October 1999 until its closure in April 2001.

Adamo grew up in New York City, where she worked as a child and adult model for Ford Models. Before deciding to become a professional wrestler, Adamo held a series of other jobs, including tending bar, working as a donut stuffer for Country Donuts, working as a booker for a modeling agency, working as a fitting model, performing as an oil wrestler at the strip clubs Billy Dean's and Goldfingers, and working as a booker for go go bars. In the late 1990s, Adamo decided to become a professional wrestler. She was trained as a professional wrestler by The Fabulous Moolah in South Carolina and by Johnny Rodz in New York City. She debuted in 1999 under the ring name "Elektra". Elektra appeared on the April 5, 1999 edition of WWF Raw is War, playing one of The Godfather's "hos" during his match with WWF Intercontinental Champion Goldust.

Elektra debuted in Extreme Championship Wrestling in October 1999 at Re-enter the Sandman, with Cyrus presenting her to Danny Doring as a replacement for Miss Congeniality. She went on to act as a valet for Doring and his tag team partner, Roadkill, interfering in their matches and fighting with opposing valets such as Francine. Elektra became known for her ability to flex her pectoralis major muscles, which she would often do while delivering promos. At Living Dangerously on March 12, 2000, Elektra turned on Doring and Roadkill, costing them a match against Lou E. Dangerously's New Dangerous Alliance by unbalancing Roadkill while he stood on the top rope. Later that night, Elektra delivered a promo in which she revealed that she had joined the New Dangerous Alliance. Elektra was subsequently nicknamed the "Director of Covert Operations" of the New Dangerous Alliance. After the New Dangerous Alliance disbanded, Elektra aligned herself with EZ Money, Julio Dinero and Chris Hamrick. At Anarchy Rulz 2000 on October 1, Elektra accompanied EZ Money to the ring for his match with Kid Kash. Following the match, The Sandman caned the members of Hot Commodity before spitting beer over Elektra. At the final ECW pay-per-view, Guilty as Charged 2001 on January 7, 2001, Elektra accompanied EZ Money and Julio Dinero as they unsuccessfully challenged Doring and Roadkill for the ECW World Tag Team Championship. ECW staged its final show six days later and filed for bankruptcy on April 4, 2001.

During the 2000s, Elektra made uncredited appearances as an extra in multiple episodes of the television series The Sopranos as a stripper in the "Bada Bing" strip club, scenes for which were filmed in Satin Dolls. Elektra and fellow "Bada Bing" strippers Justine Noelle, Kelly Madison Kole, Luiza Liccini, Marie Athanasiou, Nadine Marcelletti, Rosie Ciavolino and Sonia Ortega appeared in a photo spread in the August 2001 issue of Playboy magazine. Elektra intentionally lost muscle mass for the photoshoot. In June 2013, Elektra was interviewed by RTL Nieuws, expressing sadness at the sudden death of James Gandolfini, the actor who starred in The Sopranos.
