Dr Pepper is a soft drink, marketed as having a unique flavor. The drink was created in the 1880s by Charles Alderton of Waco, Texas and first served around 1885. Dr Pepper was first nationally marketed in the United States in 1904 and is now also sold in Europe, Asia, Canada, Mexico, Australia and New Zealand (as an imported drink) and South America. Variants include a non-high fructose corn syrup version, Diet Dr Pepper, as well as a line of versions with additional flavors, first introduced in the 2000s.

W.W. Clements, a former CEO and president of the Dr Pepper/7-Up Company, described the taste of Dr Pepper as one-of-a-kind, saying "I've always maintained you cannot tell anyone what Dr Pepper tastes like because it's so different. It's not an apple, it's not an orange, it's not a strawberry, it's not a root beer, it's not even a cola. It's a different kind of drink with a unique taste all its own."
