The Baltimore Orioles are an American professional baseball team based in Baltimore. The Orioles originally formed as the Milwaukee Brewers in 1894, moving to St. Louis after the 1901 season, becoming the St. Louis Browns. Finally, after 52 years as the Browns, the franchise was acquired by a partnership of Baltimore businessmen who renamed the team the Baltimore Orioles.

As the Brewers, Browns, and Orioles the franchise have participated in 124 seasons in the American League, making the playoffs 15 times, winning 7 pennants and 3 World Series championships (against the Los Angeles Dodgers in 1966, the Cincinnati Reds in 1970, and the Philadelphia Phillies in 1983).^[1] Through October 12, 2023 they have played 19,042 games, winning 9,029 and losing 10,013 for a win-loss record of 0.474.^[2]

Cal Ripken Jr. holds the most team records with 13, including hits, runs, RBIs, doubles, and home runs. The slugger, nicknamed "The Iron Man", also holds the record for consecutive games played (2,632), surpassing Lou Gehrig on September 6, 1995 with his 2,131st consecutive game played.^[3] Jim Palmer holds the most pitching records for the Orioles, including wins, games played, strikeouts, and shutouts.^[4] Palmer is the only pitcher in Major League history to win World Series games in three decades, and over his 558 games played never surrendered a single grand slam.

This is a list of team records for the Baltimore Orioles. Records from or before 1901 were as the Milwaukee Brewers, and between 1902 and 1954 as the St. Louis Browns.

These are the individual records for Batting^[5] and Pitching^[6] over the course of player's careers with the franchise.
