Brooks Calbert Robinson Jr. (May 18, 1937 – September 26, 2023) was an American professional baseball player who played his entire 23-year career in Major League Baseball (MLB) as a third baseman for the Baltimore Orioles from 1955 to 1977. Nicknamed "Mr. Hoover" and "the Human Vacuum Cleaner", he is generally considered to have been the greatest defensive third baseman in major league history.

An 18-time All-Star, he won 16 consecutive Gold Glove Awards, the most by a position player, and tied with Jim Kaat for the second-most of all time, behind Greg Maddux. His 2,870 career games at third base not only exceeded the closest player by nearly 700 games when he retired, but also remain the most games by any player in major league history at a single position. His 23 seasons spent with a single team set a major league record since matched only by Carl Yastrzemski.

Joining the Orioles as a teenager in 1955, Robinson became the centerpiece of the team as they posted the best record in the major leagues between 1965 and 1974, capturing four American League (AL) pennants and two World Series titles. Beloved in Baltimore, Robinson was known as "Mr. Oriole" by the team's fans. He was named the AL Most Valuable Player (MVP) in 1964 after posting career highs with a .317 batting average, 28 home runs, and 118 runs batted in (RBIs), leading the AL in the last category. In 1966, he finished second in the MVP voting behind teammate Frank Robinson after again posting 100 RBIs as the Orioles won the pennant, before sweeping the Los Angeles Dodgers for the team's first Series title.

In the 1970 World Series against the Cincinnati Reds, Robinson drew wide attention with his strong defensive play, time after time robbing Cincinnati players of base hits, and drove in runs in the first four games; his performance won him the World Series MVP Award as Baltimore defeated the Reds in five games. In 1971 he became one of just 12 players to earn over $100,000 annually. Robinson led AL third basemen in fielding percentage eleven times and in assists eight times, both major league records, and in putouts and double plays three times each. He still holds major league records for career putouts (2,697), assists (6,205), total chances (9,165), and double plays (618) at third base, with each total being between 13% and 20% higher than the closest player. His career fielding percentage of .971 was a major league record until 2006, and remains the top AL mark.

Upon his retirement during the 1977 season, his 2,896 games and 10,654 at bats each ranked fifth in major league history, behind only Ty Cobb among AL players, and his 2,848 hits ranked seventh in AL history. From 1969 to 1980, he held the AL record for career home runs by a third baseman. He set franchise records for career games, at bats, hits, runs (1,232), RBIs (1,357), doubles (482), total bases (4,270), and home runs by a right-handed hitter (268), all of which were later broken by Cal Ripken Jr. Robinson was elected to the Baseball Hall of Fame in 1983 in his first year of eligibility, a first for third basemen. Following his playing career, he served as a broadcaster for the Orioles and also joined Opening Day Partners, who own several minor league teams. Robinson remained popular with Oriole fans for his kindness and patience with them. "Never has a player meant more to a franchise and more to a city than Brooks has meant to the Orioles and the city of Baltimore," said Oriole historian Ted Patterson.

Brooks Calbert Robinson was born on May 18, 1937, in Little Rock, Arkansas, to Brooks Calbert Sr. and Ethel Mae (née Denker) Robinson. His father worked for Colonial Bakery in Little Rock and later became a captain with the Little Rock Fire Department. Meanwhile, his mother worked for Sears Roebuck & Company before accepting a position with the state controller's office. Young Robinson drew a salary himself from delivering the Arkansas Gazette on his bicycle, as well as operating the scoreboard and selling soft drinks at Lamar Porter Field.

Robinson Sr. played second base for a semi-pro baseball team. He would play the game with his son during Robinson's younger years. Growing up, Robinson rooted for the St. Louis Cardinals; Stan Musial was his favorite player. In high school, he played American Legion Baseball for the M. M. Eberts Post No. 1 Doughboys, among the greatest American Legion teams in that part of the country. The team reached the regional finals in 1952, when Robinson was 15. They then advanced to the sectional tournament in 1953. Robinson graduated from Little Rock Central High School on May 27, 1955, impressing the University of Arkansas enough with his basketball ability that the school offered him a full scholarship. However, Robinson desired to become a professional baseball player. Lindsay Deal, who went to Capitol View Methodist Church with Robinson, had been a teammate of Baltimore Orioles manager Paul Richards on a minor league team, and he wrote a letter to Richards praising Robinson's ability. "He's no speed demon, but neither is he a truck horse," Deal wrote. "Brooks has a lot of power, baseball savvy, and is always cool when the chips are down." In 1955, three major league teams sent scouts to Little Rock to try to sign Robinson: the New York Giants, the Cincinnati Redlegs, and the Orioles. Each offered $4,000, but only Cincinnati and Baltimore were offering major league contracts. Robinson ultimately chose to sign with Baltimore because the Orioles had shown the most interest and had the most opportunities for young players to become everyday players on their roster. Art Ehlers was the scout who signed him.

Playing second base, Brooks Robinson made his professional debut on June 3, 1955, at Bob Hoffman Stadium with the York White Roses. After three months in York, Pennsylvania, he made his first appearance with the Orioles on September 17, 1955, at Memorial Stadium against the Washington Senators, batting sixth in the lineup. He had two hits in four at bats, singling in the fourth inning against Chuck Stobbs for his first hit before driving in a run on a single in the eighth inning in a 3–1 win. After that, he went hitless in his next 18 at bats before sitting for the season's final two games. "Those American League pitchers made me look like just what I was—a young, green, immature eighteen-year-old who'd been lucky that first day against Washington," he later reflected. After the season, the Orioles assigned him to the Willard Blues, a Colombian winter league team where Baltimore sent some of its best prospects. Earl Wilson hit Robinson in the head with a pitch in one of the games, but Robinson was protected from severe injury because of a new fiberglass batting helmet the team was testing on their players.
