The 1981 Baltimore Orioles season was the franchise's 28th season based in Baltimore and 81st overall season as a member of the American League. Games were suspended for 50 days due to the 1981 Major League Baseball strike, causing a split season. The Orioles competed as members of the American League East, finishing second in the first half of the season and fourth in the second half of the season; their overall record was 59 wins and 46 losses. The Orioles hit five grand slams, the most in MLB in 1981.
