A food observance on March 6 celebrating the Oreo, the sandwich cookie that became the best-selling cookie in the world.
“No source names a founder. The day simply borrows the Oreo's own 1912 first-sale anniversary.
National Oreo Cookie Day has no documented founder or founding year. The undocumented food-day observance attached itself to a real anniversary: the date the National Biscuit Company (Nabisco) first sold the Oreo in 1912.
The Oreo was the knockoff. When the National Biscuit Company introduced it in 1912, the chocolate creme sandwich already had a model to copy: Hydrox, launched in 1908 by Sunshine Biscuits.
Then the imitation swallowed the original. Oreo grew so dominant that most people now assume Hydrox was the copy, not the source. The cookie this day honors got famous by out-marketing the recipe it borrowed.
That is the strange thing under National Oreo Cookie Day. It celebrates a product whose own origin is a quiet upset, and whose name, more than a century later, still has no confirmed meaning.

The cookie this day celebrates was, before anything else, a New York product. It was drawn up, mixed, and baked in one Manhattan neighborhood, and the name on the wrapper has puzzled people ever since.
That neighborhood was Chelsea. The story of the Oreo runs through a single factory there, a few naming theories no one can prove, and a corporate handoff that ended with a snack giant most shoppers have never heard of.
Nabisco baked the first Oreo at its factory on Ninth Avenue in Chelsea, the complex that is now the Chelsea Market food hall. The National Biscuit Company introduced the cookie in 1912.
The connection to the block stuck. In 2002 the city named that stretch of Ninth Avenue Oreo Way, a small civic monument to a snack. Nabisco won the trademark in 1913 and, around 1921, dropped the original Oreo Biscuit name for Oreo Sandwich.
One thing the record cannot settle is what Oreo means. The leading guesses run from the French or, for the gold of the early packaging, to the Greek oros, for an early hill or mound shape, to the simple idea that it was just short and easy to say.
Pastry historian Stella Parks traced it instead to Oreodaphne, a laurel-family plant, noting Nabisco's habit of naming cookies after botanicals and the laurel wreath in the original design. Nabisco and its successor Mondelez have never confirmed any theory.
Ownership of the cookie moved over the decades. Nabisco passed to Kraft Foods, and on October 1, 2012, Kraft split and renamed its global snacks business Mondelez International, which owns Oreo today.
National Oreo Cookie Day, by contrast, has no such paper trail. No source names who created the observance or when. It simply fixed itself to March 6, the Oreo's own 1912 first-sale anniversary, and the brand has since leaned in, marketing the date as National Oreo Day.
