Offermann Stadium was an outdoor baseball and football stadium in Buffalo, New York. Opened in 1924 as Bison Stadium, it was home to the Buffalo Bisons (IL), Buffalo Bisons/Rangers (NFL) and Indianapolis Clowns (NAL).

The stadium hosted the Little World Series (1927) and the Junior World Series (1933, 1936 and 1957). The venue also hosted summer boxing cards, most famously the 1930 bout between future International Boxing Hall of Fame members Jimmy Slattery and Maxie Rosenbloom.

The venue was demolished in 1961 and is now the site of Buffalo Academy for Visual and Performing Arts.

Bison Stadium was built on the former site of Buffalo Baseball Park for $265,000. The wooden grandstands from the prior venue, designed by famed architect Louise Blanchard Bethune, were preserved and incorporated into the new steel and concrete facility.

The ballpark was built in the middle of a residential neighborhood on a rectangular block, and was known as a hitter's park because of its small dimensions.

National Baseball Hall of Fame member Tommy Lasorda described how the small dimensions of the venue were unfavorable to pitchers like himself in a May 1997 interview:

I used to curse Offermann Stadium. I'd look over my shoulder and the left-field wall was right behind me.

Homeowners on Masten Avenue behind left field and Woodlawn Avenue behind right field erected "bootleg bleachers" on their rooftops, charging fans admission to watch games.
