The Wisconsin Timber Rattlers are a Minor League Baseball team of the Midwest League and the High-A affiliate of the Milwaukee Brewers. They are located in Grand Chute, Wisconsin, a town on the outskirts of Appleton in the Fox Cities, and are named for the timber rattlesnake, which is more commonly found in southwest Wisconsin. The team plays their home games at Neuroscience Group Field at Fox Cities Stadium, which opened in 1995. They previously played at Goodland Field from their founding in 1958 until the end of the 1994 season.

The Midwest League Manager of the Year Award is an annual award given to the best manager in Minor League Baseball's Midwest League based on their regular-season performance as voted on by league managers. Broadcasters, Minor League Baseball executives, and members of the media have previously voted as well. The award was created in the league's inaugural 1947 season. The circuit was known as the Illinois State League from 1947 to 1948 and as the Mississippi–Ohio Valley League from 1949 to 1955 before becoming the Midwest League in 1956. After the cancellation of the 2020 season, the league was known as the High-A Central in 2021 before reverting to the Midwest League name in 2022.
