Baltimore Country Club

The club opened in 1898 in its 125-acre (51 ha) Roland Park location with a membership of approximately 1,000. Just one year after opening, the Club hosted the fifth United States Open Championship, which was won by Willie Smith of Scotland. By the 1920s the decision was made to acquire land to the north of the city and expand the popular golfing amenities to a second location. The East Course at Five Farms, designed by A. W. Tillinghast, officially opened in September 1926. Two years later, this new course held the 1928 PGA Championship.

In October 1930, the Roland Park Clubhouse sustained fire damage, and prior to completing repairs, it was virtually destroyed by a second fire on January 5, 1931. The new "in-town" Clubhouse was formally opened on April 1, 1932. The Federal-style detailing of the Georgian Room, the paneling and black Belgian marble of the foyer, and the rough stone and pine of the Grille remain practically unchanged to this date. The duckpin bowling lanes were built in 1932 and remain in use today. During the late 1930s and early 1940s the grass tennis courts at Roland Park were selected by the National Lawn Tennis Association to host the qualifying rounds for the Davis Cup matches. Teams from Australia, Cuba, Japan, Mexico, Spain, and the United States all participated. The Roland Park Golf Course was officially closed in 1962 when all of the property on the west side of Falls Road was sold. That same year, the West Course at Five Farms opened. Two years later, the stately Olivier Mansion, which served as the original Five Farms Clubhouse, was demolished and replaced with a new building.

The businessman Nicholas Mangione alleged that he experienced anti-Italian discrimination at the Baltimore Country Club during the 1970s.

Squash courts, now international, were added to the Roland Park facility in 1963. The Club continues to host professional squash tournaments. The Club expanded its racquets program and added paddle tennis courts to the Roland Park campus in 1976. The club's swim complex was first built circa 1960. Renovations began some thirty years later, and the current facility, consisting of three independent pools, opened at Five Farms in 1996. New tennis courts, also at Five Farms, debuted in 2007.

Starting in the fall of 2021, the clubhouse at Five Farms underwent a major renovation. The renovation remodeled nearly all of the first floor of the building, expanding the grill, adding a formal dining room, outdoor covered bar area and a rooftop bar. It opened in late summer of 2022.
