Deer have long had economic significance to humans. Deer meat, known as venison, is highly nutritious. Due to the inherently wild nature and diet of deer, venison is most often obtained through deer hunting. In the United States, it is produced in small amounts compared to beef, but still represents a significant trade. Deer hunting is a popular activity in the U.S. that can provide the hunter's family with high quality meat and generates revenue for states and the federal government from the sales of licenses, permits and tags. The 2006 survey by the U.S. Fish and Wildlife Service estimates that license sales generate approximately $700 million annually. This revenue generally goes to support conservation efforts in the states where the licenses are purchased. Overall, the U.S. Fish and Wildlife Service estimates that big game hunting for deer and elk generates approximately $11.8 billion annually in hunting-related travel, equipment and related expenditures. Conservation laws prevent the sale of unlicensed wild game meat, although it may be donated.

Deer have often been bred in captivity as ornaments for parks, but only in the case of reindeer has thorough domestication succeeded. By 2012, some 25,000 tons of red deer were raised on farms in North America. The Sami of Scandinavia and the Kola Peninsula of Russia and other nomadic peoples of northern Asia use reindeer for food, clothing, and transport. Others are bred for hunting are selected based on the size of the antlers. The major deer-producing countries are New Zealand, the market leader, with Ireland, Great Britain and Germany. The trade earns over $100 million annually for these countries.

Automobile collisions with deer can impose a significant cost on the economy. In the U.S., about 1.5 million deer-vehicle collisions occur each year, according to the National Highway Traffic Safety Administration. Those accidents cause about 150 human deaths and $1.1 billion in property damage annually. In Scotland, several roads including the A82, the A87 and the A835 have had significant enough problems with deer vehicle collisions (DVCs) that sets of vehicle activated automatic warning signs have been installed along these roads.

The skins make a peculiarly strong, soft leather, known as buckskin. There is nothing special about skins with the fur still on since the hair is brittle and soon falls off. The hooves and antlers are used for ornamental purposes, especially the antlers of the roe deer, which are utilized for making umbrella handles, and for similar purposes; elk antlers is often employed in making knife handles. Among the Inuit, the traditional ulu women's knife was made with an antler or ivory handle. In China, a traditional chinese medicine is made from stag antler, and the antlers of certain species are eaten when "in the velvet". Antlers can also be boiled down to release the protein gelatin, which is used as a topical treatment for skin irritation and is also used in cooking.

Since the early 20th century, deer have become commonly thought of as pests in New Zealand due to a lack of predators on the island causing population numbers to increase and begin encroaching on more populated areas. They compete with livestock for resources, as well as cause excess erosion and wreak havoc on wild plant species and agriculture alike. They can also have an effect on the conservation efforts of other plant and animal species, as they can critically offset the balance within an environment by drastically depleting diversity within forests.
