Dunkin’ brings back Iced Coffee Day, with $1 donations per cup

Dunkin’ will bring back Iced Coffee Day on May 27, with $1 from every iced coffee and cold brew sold at participating U.S. locations going to the Dunkin’ Joy in Childhood Foundation. The one-day promotion gives customers a clear takeaway: buy a cold coffee, and a dollar from that purchase goes to a charity program tied directly to the brand.

The foundation supports food banks, children’s hospitals and nonprofit organizations, so the event reaches beyond a standard beverage discount or seasonal special. It turns a cold coffee run into a fundraising moment, with the sale of core summer drinks doing double duty as traffic driver and community support.

This will be the fifth year for the campaign, and Dunkin’ said Iced Coffee Day generated more than $2 million in grants in 2025. Franchisee leader Victor Carvalho has framed the event as a way to turn an everyday routine into something more meaningful, a pitch that helps explain why the promotion keeps coming back.

The timing also fits Dunkin’s warm-weather menu strategy. Iced coffee and cold brew are central to the brand’s summer lineup, and a limited-time event like this gives the chain a reason to pull attention toward those drinks at exactly the point when cold coffee starts to dominate daytime orders. For a mass-market coffee chain, that matters as much as the donation itself.

The broader pattern is familiar across big coffee brands: a single day can do more than move drinks. It can lift store traffic, strengthen loyalty, and generate social sharing around a message that feels bigger than a beverage. Dunkin’ has built Iced Coffee Day around that formula, using a cup of iced coffee or cold brew to signal both seasonal momentum and a public-facing charitable push.

When customers head in on May 27, the appeal will be straightforward. The chain’s cold coffee staples will be on sale as usual, but each cup will also carry a $1 donation to the foundation, which is exactly why this promotion has become a repeat fixture rather than a one-off stunt.
