Varzea Grande EC

The club was founded on 8 August 2002 in the place of Esporte Clube Operário, which was then founded in 1994 to replace dissolved side CE Operário Várzea-Grandense. After inheriting ECO's place, the club played in the 2003 Copa do Brasil and was knocked out by Palmeiras.

In 2005, Operário lifted their first trophy by winning the year's Copa FMF, after defeating Mixto in the finals. They also won the Campeonato Mato-Grossense in the following year, after defeating Barra do Garças, and played in the ensuing Campeonato Brasileiro Série C.

In 2009, after the latter returned to an active status, a merger proposal was lifted, but the move did not materialize. In that year, Operário FC played in the first division, while CEOV played in the second division. CEOV was again licensed in 2010, as Operário finished second in that year's Matogrossense.

Both CEOV and Operário FC faced each other in 2013, 2016, 2017 and 2019; both were playing in the second division in the first encounters, while the remaining ones all took part in the first division. In 2017, after being relegated to the second level, Operário was sold through a social media.

In 2018, Operário FC changed colours to differentiate from CEOV. In 2019, after being relegated from the first division, Operário chose not to play in the 2020 second division.

In 2025, the club changed its name to Várzea Grande EC, differentiating itself once and for all from CEOV. The club's president, Atahide Mello, says the change aims to enhance the city of Várzea Grande.
