Bang & Olufsen, Jysk, Louis Poulsen, Royal Greenland, VELUX and Vestas, not to mention Maersk. Although it's "just" Scandinavian, please fly SAS when you travel!
Thanks to commenter Erik:
Also if you live on the West Coast (or near a Trader Joe's): TJ's Potoato Medley and Fire Roasted Vegetables (in the frozen foods section) are "Product of Denmark". And they're economical, easy to fix, and mighty tasty too.
