Buenos Aires Lawn Tennis Club, Tennis club in Palermo, Buenos Aires, Argentina

The Buenos Aires Lawn Tennis Club is a sports club in the Palermo neighborhood with multiple tennis courts for matches and training. The main stadium, the Horacio Billoch Caride Stadium, holds around 5,500 spectators and hosts professional tournaments.

The club was officially founded on 19 April, with Arthur Herbert as president, after a letter from six promoters to the British community proposed the idea; the first match, against Rosario players, was played on 29 June 1892. It moved to land beside the Central Argentine Railway's golf course, inaugurated on 12 June 1920, where it has remained. It was a founding member of the Argentine Tennis Association on 2 September 1921.

The club's honorary members include Guillermo Vilas, Enrique Morea, Norma Baylon and Gabriela Sabatini. Vilas began his career at BALTC at 15 and debuted for Argentina in the 1970 Davis Cup tie against Chile held here. The main court was renamed Court Central Guillermo Vilas in 2017, though a 2015 proposal to rename the stadium itself after him did not succeed.

The club is private, so access to the grounds is not open to the general public; the Horacio Billoch Caride Stadium is the main court where the decisive rounds are played. The usual surface is clay, but during the December Peugeot Argentina Tennis Cup exhibition the stadium is converted to hard court. The club sits in Palermo, and the stadium is bordered by smaller clay courts and trees.

In 2018 the grounds hosted all tennis events for the Youth Olympic Games, marking a major milestone in the club's history. This event brought international attention to the facility and its role in global tennis.
