The Wait Is Over: Shamrock Shake Returns to McDonald’s

February 5, 2025

It’s the once-a-year gift that keeps on giving. McDonald’s Shamrock Shake has returned to the fast-food chain’s menu.

However, this year, McDonald’s is bringing back a ’70s-era character, who has been on a decades-long hiatus, to usher in the return of the beloved frosty beverage — Uncle O’Grimacey, Grimace’s uncle who hails from Sham Rock, Ireland.

A press release states, “This Shamrock Season celebration came to life when Grimace stumbled upon his family’s original Shamrock Shake recipe. That discovery sparked Grimace to reconnect with his vibrant, joyful, and generous uncle, Uncle O’Grimacey.”

The release continues, “Inspired to reunite with Grimace and support his favorite Charity’s 50th milestone, Uncle O’Grimacey packed his bags and embarked on a journey from Sham Rock, Ireland. Now that he’s here, Uncle O’Grimacey is traveling coast-to-coast, spreading Shamrock cheer with fans everywhere and celebrating RMHC and their mission to keep families together.”

For fans who want to publicly display their love for the Shamrock Shake and to raise even more money for RMHC, the fast-food giant is also selling special merchandise featuring Uncle O’Grimacey and other McDonald’s favorites. This swag is available for pre-sale now at goldenarchesunlimited.com. Customers can also round up their purchases to support RMHC at their local McDonald’s restaurants.

“Our fans eagerly await the Shamrock Shake each year. We are thrilled that proceeds from this minty-flavored treat will aid RMHC in keeping families together,” says Joy Silmon, second-generation McDonald’s franchisee. “Family is a core value at McDonald’s, and we live this every day. Together, with our Crew, customers, and iconic McDonaldland character, Uncle O’Grimacey, we’re helping RMHC make families feel at home, even when they can’t be.”

McDonald’s Celebrates the 50th Anniversary of Ronald McDonald House Charities

Shamrock Shake season is part of the yearlong anniversary celebration of the Gift to RMHC program. It honors the ongoing fundraiser that helped to open the doors of the first Ronald McDonald House in 1974.

The Ronald McDonald House Charities (RMHC) is a nonprofit organization that provides housing and support for families with seriously ill or injured children receiving medical care. The organization was founded in 1974 in Philadelphia, Pennsylvania, through a partnership between McDonald’s, the Philadelphia Eagles, and local doctors. Since its inception, McDonald’s, its franchisees, and its customers have collectively donated over $1 billion to RMHC.

“Our long-standing tradition of the Shamrock Shake is a testament to the joy we bring to our customers. This year, we are getting back to the first fundraiser that started our incredible partnership with RMHC,” said Michael Gonda, chief impact officer, North America at McDonald’s. “This Shamrock Shake Season, with a little extra cheer from the Grimace family, we’re reminded that the most precious gift is being close to those you love.”

For every Shamrock Shake purchased from Feb. 10 through March 23, 2025, at participating McDonald’s, 25 cents will be donated to RMHC. The fast-food restaurant has a goal of raising $5 million. This donation could provide 50,000 overnight stays for families staying at RMHC programs.
