Harvey's red duiker (Cephalophus harveyi) is one of 19 species of duiker found in Tanzania and scattered through Kenya, southern Somalia, and, possibly, central Ethiopia.

Harvey's duikers are roughly 40 centimetres tall at the shoulder and weigh around 15 kilogrammes, on average. They have a mostly chestnut coat, but their legs and face are black.

Harvey's duikers live in mountain and lowland forest, where they eat leaves, twigs, fruit, insects, birds eggs, and carrion. Although this duiker is not endangered, it is dependent on protected forestland. As of 2008, this species is a Least concern.

Harvey's is a fast food restaurant chain that operates in Canada, with locations concentrated in southern Ontario, southern Quebec, as well as the Maritimes, Manitoba, British Columbia, and Alberta. It serves hamburgers, hot dogs, french fries, onion rings, and other traditional fast food fare. The chain is owned by Cara Operations. Harvey's is the second-largest Canadian-established restaurant chain behind Tim Hortons, and is the fourth-largest burger chain in Canada.

Harvey's is known for its grilled from frozen burgers, allowing customers the choice of 11 different toppings, including lettuce, pickles, tomatoes, onions, hot peppers, and a wide selection of condiments ranging from ketchup, mustard, BBQ sauce, mayonnaise to Frank's Red Hot sauce. Cooked burgers are placed in view of the customer, behind a glass counter, while an employee garnishes the burger as per the customer's choice before wrapping it in paper and serving it to them. In this sense, Harvey's is closer to the model used by submarine sandwich chains like Subway, as opposed to other burger chains which use a set list of toppings for each burger, omitting toppings only at the customer's specific request.
