Bribery is the act of giving or receiving something of value in exchange for some kind of influence or action in return, that the recipient would otherwise not alter. Bribery is defined by Black's Law Dictionary as the offering, giving, receiving, or soliciting of any item of value to influence the actions of an official or other person in charge of a public or legal duty. Essentially, bribery is offering to do something for someone for the expressed purpose of receiving something in exchange. Gifts of money or other items of value which are otherwise available to everyone on an equivalent basis, and not for dishonest purposes, is not bribery. Offering a discount or a refund to all purchasers is a legal rebate and is not bribery. For example, it is legal for an employee of a Public Utilities Commission involved in electric rate regulation to accept a rebate on electric service that reduces their cost for electricity, when the rebate is available to other residential electric customers. Giving the rebate to influence them to look favorably on the electric utility's rate increase applications, however, would be considered bribery.

A bribe is the gift bestowed to influence the recipient's conduct. It may be money, goods, rights in action, property, preferment, privilege, emolument, objects of value, advantage, or merely a promise to induce or influence the action, vote, or influence of a person in an official or public capacity.

Many types of payments or favors can constitute bribes: tip, gift, sop, perk, skim, favor, discount, waived fee/ticket, free food, free ad, free trip, free tickets, sweetheart deal, kickback/payback, funding, inflated sale of an object or property, lucrative contract, donation, campaign contribution, fundraiser, sponsorship/backing, higher paying job, , secret commission, or promotion (rise of position/rank).
