Established in 1930, the Vaqueros de Bayamon—initially known as Bayamon—quickly made their mark in the amateur Baloncesto Nacional league, now the Baloncesto Superior Nacional (BSN). Under the guidance of Professional Head Coach Onofre Carballeira, they clinched their first league championships in 1933 and 1935. However, the team's momentum was interrupted in the 1940s due to WWII, and their participation only resumed in 1954.

With the return of competition, the team underwent a rebranding as the Azules de Bayamón (lit. "Bayamon Blues"), led by Coach Félix Joglar. Despite the renewed effort, the team did not secure any titles that season.

The team entered its modern era shortly after, rebranding as Los Vaqueros de Bayamon in 1955, the new name was inspired by their new sponsor, Espasas Dairy Company. This era marked a significant comeback for the team.

During this time, the Vaqueros roster boasted remarkable talents. Evelio Torres, who joined in 1957, quickly became a star, leading the league in scoring with 407 points in 1959, and representing Puerto Rico in the Central American and Caribbean Games in Venezuela. Martin Gaínza, known as one of the most offensive players in Puerto Rican basketball history, joined the team in 1960 and won the scoring title with 405 points.

In 1967, the Vaqueros secured a championship win against the Ponce team, their third championship and their first in 32 years. This victory, partially attributed to the sportsmanship and skills of players like Julio Toro, marked the beginning of a resurgence for the Vaqueros. They consolidated this newfound reputation with another championship in 1969.

The 1970s became a golden era for the Vaqueros, with the team winning five consecutive championships from 1971 to 1975. Under the influence of notable coaches such as Roy Rubbins, Art Loche, Lou Rossini, Fufi Santori, Tom Nissalke, and Del Harris, the Vaqueros continued to excel. Fufi Santori, a figure renowned both as a player and coach, played a pivotal role during this period, as did exceptional defensive player Alberto Samot.

As the 1980s arrived, competition in the BSN intensified, particularly against the Guaynabo Mets team, led by Mario Morales and Federico Lopez. The Vaqueros emerged victorious in the final series against Guaynabo in 1981, adding another championship to their collection.

The team's fanbase saw considerable growth in the 1980s and 1990s. In 1988, under the guidance of Robert Corn, the Vaqueros clinched yet another championship against the Indios de Canovanas. They secured further championships in 1995 and 1996 against the Ponce Lions, with Flor Melendez serving as head coach.

The late 1990s and the early 2000s, however, proved to be a challenging period for the Vaqueros. From 1999 to 2008, the team often struggled to advance beyond the semifinals, only making it to the finals in 2005, where they were defeated by the Arecibo Captains. This period marked a decline in the franchise's performance, prestige, and fanbase.

The team's fortunes turned in 2009 when new management sought to invest heavily in the franchise recruiting talents like: Christian Dalmau, Orlando 'Guayacan' Santiago, Carmelo Lee, Danny Santiago and Olumide Oyedeji; that year they won a championship against Quebradillas, effectively ending a decade of stagnation. Although the 2010s saw a competitive yet unsuccessful championship bid, marking their first title-less decade since the 1950s, the Vaqueros found their stride again in the next decade. Under the leadership of Coach Nelson Colon, they celebrated championship wins in 2020 ( a condensed tournament season given the extraordinary COVID-19 pandemic) and again in 2022, bringing their total league titles to sixteen. As a result, they surpassed the San German Athletics in the league's historical standings. As of now, the Vaqueros de Bayamon are the reigning champions in the BSN league, demonstrating a remarkable return to form in the current decade.
