SOUTH BEND, Ind. – The 2026 Shamrock Series logo serves as a visual combination of the history of two storied football programs and one of the most iconic NFL stadiums for the upcoming clash between Notre Dame and Wisconsin at Lambeau Field this fall.
The event logo is built on weaving together the storied past of Lambeau Field and Wisconsin-inspired elements. The location and history of Lambeau Field sets the tone for the foundation of the logo. The primary color scheme of green and gold along with the bricks and pillars are direct representations of the stadium itself. The foundational color – Stadium Green – evokes the primary color of Lambeau Field. The gold of the pennant and detailed outline is representative of the Packers’ organization while serving as a nod to the gold of Notre Dame.
The Notre Dame and Wisconsin street signs pay homage to the location of Lambeau Field – amid a neighborhood in the working town of Green Bay, Wisconsin. Each team’s sign is in their respective primary colors as the two teams are set to come together on the field in a crossroads of competition for just the 18th time overall and the first time since 2021.
The font treatment of the words “Shamrock” and “Series” both honor the locale of this year’s game. The inspiration for the word “Shamrock” was drawn from the blue-collar brands and industries of Wisconsin throughout the 1960s and 1970s. Lambeau Field’s unique font, meanwhile, is represented in the treatment of the word “Series”. The two words are joined together at their bases with a football in flight.
Below the Shamrock Series word treatments is a gold pennant with the year 2026. The design is a direct representation of the championship banners displayed by the Green Bay Packers franchise throughout Lambeau Field.
The wheat stalks at the base of the logo flanking the shamrock incorporate the Notre Dame Founder’s Lines. The wheat is symbolic of the agricultural impact of the state of Wisconsin while the lines are representative of the year of the founding of the University.
The presenting sponsor of the event – Credit Union 1 – is prominently featured at the base of the logo as their support helps continue the longstanding legacy of the Shamrock Series contest.
The 2026 Shamrock Series is set to take place on Sunday, September 6 at Lambeau Field in Green Bay, Wisconsin. The game is scheduled for 7:30 p.m. ET/6:30 p.m. CT and will air on NBC and Peacock.
