Loudoun United FC

On July 18, 2018, the team was officially announced by USL and D.C. United as were the team's name, colors and crest. Loudoun United FC replaced Richmond Kickers as D.C. United's USL affiliate.^[1]

After the founding of MLS Next Pro in 2022 and the subsequent movement of MLS reserve teams to that league by 2023, Loudoun United remained the only MLS-affiliated reserve side in the USL system; due to a legal agreement for leasing Segra Field, United is required to play in the second division.

On February 2, 2023, Loudoun United FC was sold to Attain Sports and Entertainment, which owns minor league baseball teams Bowie Baysox and Frederick Keys.^[3] D.C. United will continue to own a minority stake in Loudoun United.^[2] Furthermore, the change of ownership also meant that Loudoun United was eligible to participate in the 2023 U.S. Open Cup.^[4]

On April 17, 2025, it was announced that Loudoun United FC would merge with the Virginia Revolution Soccer Club, a youth and pre-professional soccer club with teams in MLS Next and the United Premier Soccer League.^[5] As part of this merger, the club announced on December 2, 2025 that the united organization would host a pre-professional team in USL2, in the Chesapeake Division of the Eastern Conference, known simply as Loudoun United FC 2.^[6] VA Revolution coach Matthew Mountford was tapped to be the coach of this new team,^[7] with their debut set for the 2026 season. Loudoun United later announced the formation of a women's team under their same organization and brand, to play in the Mid Atlantic Division of the USL W League in 2026.^[8]

Loudoun United FC colors are black, red and white, the same as, at the time, parent club D.C. United. The club's crest contains the red-and-white gyronny seen in the flag and coat of arms of Loudoun County, as well as a winged horse in homage to both D.C. United's eagle logo and the county's long association with equestrian sports.^[9]

The club plays at Segra Field, a new 5,000-seat stadium at Philip A. Bolen Memorial Park in Leesburg. The stadium was built by D.C. United and the county government for $15 million.^[13][14] Construction began in 2018, and was completed in August 2019. After playing some initial home games at Audi Field, they debuted in their new stadium in a game against the Charlotte Independence that ended 3–3 in front of 5,015 spectators.^{[citation needed]}
