An entrepreneur (ⁱ/ˌɒntrəprəˈnɜr/) is an owner or manager of a business enterprise who makes money through risk and/or initiative. The term was originally a loanword from French and was first defined by the Irish-French economist Richard Cantillon. Entrepreneur in English is a term applied to a person who is willing to help launch a new venture or enterprise and accept full responsibility for the outcome. Jean-Baptiste Say, a French economist, is believed to have coined the word "entrepreneur" in the 19th century - he defined an entrepreneur as "one who undertakes an enterprise, especially a contractor, acting as intermediatory between capital and labour".

Entrepreneurs become what they are for several reasons. Many, depending on the person, choose to do so to avoid workplace drama, discrimination, being taken advantage of, or just to be their own boss. Another reason people become entrepreneurs is to avoid unemployment and attain job security. When an individual cannot find work, he or she may see starting a business enterprise as a suitable alternative and a good way to ensure he or she is never fired.
