Oreo made the announcement in an Instagram video, where the word Oreo transforms into the series' hashtag, #ForTheThrone.
Brewery Ommegang and HBO have also released the latest beer in their multi-year, multi-beer partnership.
"For the Throne" beer is a tribute to those who aspire to be the final occupant of the Iron Throne. This 9.5 percent ABV strong golden ale is co-fermented with pinot grigio and viognier grape juices and then bottle conditioned with Champagne yeast to create an ale fit for royalty.
HBO's fantasy drama will air its final season premiere on April 14.
