The 1999 World Series was the championship series of Major League Baseball's (MLB) 1999 season. The 95th edition of the World Series, it was a best-of-seven playoff between the defending American League (AL) and World Series champion New York Yankees and the National League (NL) champion Atlanta Braves in a rematch of the 1996 World Series, in which the Yankees prevailed. The Yankees swept the 1999 Series in four games for their second consecutive title, third in four years, and 25th overall. It was the Yankees' third straight defeat of the Braves franchise in the Fall Classic (having beaten the Milwaukee Braves in the 1958 World Series in addition to their 1996 victory over the Atlanta Braves). Yankees closer Mariano Rivera was named the World Series Most Valuable Player. This was the second World Series after 1995 since the advent of the three-division era to feature both number-one seeds from the AL and NL, a phenomenon that has only occurred thrice since: in 2013; 2020; and 2024.
The Yankees advanced to the World Series by defeating the Texas Rangers in the AL Division Series, three games to zero, and then the Boston Red Sox in the AL Championship Series, four games to one. The Braves advanced to the series by defeating the Houston Astros in the NL Division Series, three games to one, and then the New York Mets in the NL Championship Series, four games to two. The 1999 Series is remembered for Chad Curtis's walk-off home run in Game 3, which gave the Yankees a 6–5 victory, and Game 2's infamous interview of Pete Rose by Jim Gray on NBC.
