Buenos Aires Cricket & Rugby Club, sometimes known simply as Buenos Aires, is an Argentine sports club based in San Fernando, Buenos Aires. The club claims to be the oldest club still in existence in Argentina, according to reports of a cricket match played by the club in Recoleta, Buenos Aires, in 1831. Likewise, the Buenos Aires FC (established in 1886 as a rugby union club exclusively and founder member of the "River Plate Rugby Championship", current Argentine Rugby Union) merged to BACC in 1951. Since then, rugby union became the main sport of the institution.
