New England Championship Wrestling (NECW) is a dormant independent professional wrestling promotion based in the Northeastern United States that promoted events from 2000, owned and operated by Sheldon Goldberg. Its roster included independent wrestlers Antonio "The Promise" Thomas, Slyk Wagner Brown and Rick Fuller. Its women's division, World Women's Wrestling, included Ariel, Sumie Sakai, Alere Little Feather, Riptide, Nikki Roxx, Lexxus, April Hunter, Malia Hosaka and Mercedes Martinez. The promotion has not held events since 2019, though it still posts a periodic podcast.

World Wrestling Entertainment wrestlers Kofi Kingston, John Cena, Kenny Dykstra, Sasha Banks and R. J. Brewer also competed in the promotion during their early careers. Former WWE announcer and current Ring of Honor announcer Kevin Kelly worked as a booker for the promotion. Former state senator and current mayor of Weymouth, Massachusetts, Robert Hedlund, served as NECW Commissioner in 2000–2001.

Former editor of the Mat Marketplace newsletter, Sheldon Goldberg had been involved with promoters Tony Rumble and Paul Heyman in bringing Michinoku Pro to the United States during the late 1990s. By September 2000, Goldberg himself began holding professional wrestling events in the Boston-area, successfully selling out local venues such as Good Time Emporium in Somerville and the National Guard Armory in Quincy. Over the next several years, the promotion developed a strong following based on its traditional "family-friendly" style of professional wrestling as an alternative to the adult themed sports entertainment adopted by World Wrestling Entertainment.

In 2004, the promotion became the first to produce a weekly wrestling TV show specifically produced for distribution on the Internet through its affiliate NECW.tv website. Its weekly internet broadcasts eventually grew to an average of over 20,000 viewers per week in over 40 countries around the world. Its exposure was further increased through DVD releases of yearly supercards such as the popular Iron 8 Championship Tournament.

In March 2006, New England Championship Wrestling merged with PWF Mayhem and the company operated under the New England Championship Wrestling brand. On August 16, 2006, the merged companies unified their championship titles in an interpromotional event in Quincy, Massachusetts. The event saw PWF Mayhem Tag Team Champions The Canadian Superstars (J-Busta & Dave Cole) defeat The Wild Boys (Billy King & Mike Lynch) for the NECW Unified Tag Team Championship, PWF Mayhem Junior Heavyweight Champion "The Talent" T.J. Richter defeated "Big Guns" Frankie Arion for the NECW Unified Television Championship and PWF Mayhem Heavyweight Champion "The Human Nightmare" Evan Siks defeated D.C. Dillinger for the NECW Undisputed Triple Crown Championship.

Also in March 2006, the company launched World Women's Wrestling, an all-female offshoot of the main NECW promotion.

Following its "Toxic Waltz" event on November 6, 2010, the merged company ceased operations due to a split between founder, Sheldon Goldberg and the PWF faction of Matt West, Kyle White and Roy Rossi. NECW was dormant until May 14, 2011, when the company returned with a benefit show in Carver, Massachusetts. The promotion has returned to active status running regular events mostly throughout the Greater Boston area, while the revived PWF Northeast promotion only lasted until October 2013, when it ceased operations.

After the split with the PWF promoters, NECW had a 90 week run on local broadcast TV station WMFP. NECW continued running regular events and Internet TV shows up until October 2017 when promoter Sheldon Goldberg suffered a badly broken shoulder in a fall. After his recovery, the promotion resumed on a much lighter schedule and put on two charity fundraisers in 2018 and 2019. Once the pandemic hit, NECW had abandoned plans to run live events, but in 2020 NECW released a 20th Anniversary Collection on YouTube, consisting of 20 matches that represented 20 years of the promotion. New video projects are in the works with a collection of "lost matches" set for release in the fall of 2024.
