Fundraising is the process of soliciting and gathering money by requesting donations from individuals, businesses, charitable foundations, or governmental agencies. Although fundraising typically refers to efforts to gather funds for not-for-profit organizations, it is sometimes used to refer to the identification and solicitation of investors or other sources of capital for for-profit enterprises.

Fundraising is the primary way that non-profit organizations obtain the money for their operations. These operations can involve a very broad array of concerns such as religious or philanthropic groups such as research organizations, public broadcasters, and political campaigns. When special events are arranged to raise funds, they are often known as fund drives, pledge drives, capital campaigns, or, sometimes when television is involved, telethons.
