Butler Bulldogs

Butler Bulldogs is the athletic identity of Butler University in Indianapolis, Indiana. Its visual identity centers on a bulldog head logo, updated in 2019 to blue, dark gray and light gray, and unchanged in the 2025 institutional refresh.

Butler Bulldogs is the athletic identity of Butler University in Indianapolis, Indiana. The program’s visual identity centers on a bulldog head logo, which the university treats as a registered trademark alongside the phrases “Butler University,” “Butler,” and “The Butler Way.”[1]

Design and History

The primary athletics logo is a bulldog head mark. Butler’s licensing office identifies the “Bulldog head logo” as one of the university’s core registered trademarks, and the “primary athletics logo” requires a TM designation on apparel and promotional items.[1] The bulldog head has been the consistent centerpiece of the athletics identity for decades, with the head depicted head-on across successive versions.[2]

In the summer of 2015, Butler unveiled a new primary logo and a new wordmark, which were also applied to the court at Hinkle Fieldhouse.[3] That 2015 primary mark featured a bulldog head in black and dark gray.[4] In 2019, the primary logo was updated to a bulldog head rendered in blue, dark gray, and light gray.[5]

Butler’s broader institutional brand was refreshed in 2025 under the banner “Setting the Standard for Bold,” developed in partnership with the brand agency Ologie. That refresh introduced expressive typography, an expanded color palette, and new graphic elements, but the university explicitly stated that “the iconic Butler bulldog head logo remains unchanged.”[6]

Meaning and Symbolism

Butler’s official color is “Butler Blue,” identified as PMS 2767, with a four-color formula of CMYK 100/90/10/77 and web values of RGB 19/41/75 or Hex #13294b.[7] The university restricts use of the Butler logo to black, white, or Butler blue unless written approval is granted by Butler Sports Marketing.[8]

Typography and Design

Butler’s 2025 institutional brand refresh introduced “expressive typography” as part of a broader visual identity update, though the bulldog head athletics logo itself was not altered.[6] The university maintains an official style guide for its marks, which is referenced in its licensing FAQ.[8]
