The Eau Claire Bears was the primary nickname of the minor league baseball teams from Eau Claire, Wisconsin. Eau Claire was a member of the Class C Northern League (1933-1942, 1946–62) and were affiliates of the Boston Red Sox (1936), Chicago Cubs (1937-1939) and the Boston Braves (1947-1962). The team played its home games at Carson Park in Eau Claire. Baseball Hall of Fame Inductees Hank Aaron, Joe Torre and Ford C. Frick Award recipient Bob Uecker played for Eau Claire.
Originally named the Eau Claire Cardinals, the team adopted its most enduring nickname when new owners bought the team in July of its first season. Beginning in 1954, the Eau Claire Bears were renamed the Eau Claire Braves after the Boston Braves moved to Milwaukee.
The Bears, along with the rest of the Northern League, did not play the 1943-45 seasons due to World War II.
In 1998, an amateur team in Eau Claire began using the Bears name and has been a member of the Chippewa River Baseball League ever since. Along with many league titles, they also won the Wisconsin Baseball Association (WBA) state championship in 2005, 2008, and 2009.
From 1933-1938 Eau Claire played at Chappell Field, which seated 2,000 with temporary bleachers.
From 1937-1962 teams played at Carson Park, which still exists today. Built in 1937, the park had a capacity of 3500. It is located at 1 Carson Park Drive. Today, Carson Park is home to the Eau Claire Express of the summer collegiate Northwoods League and the new Eau Claire Bears of the Chippewa River Baseball League.
