"Don't be evil" is the informal corporate motto (or slogan) for Google,[1] established by company co-founder Sergey Brin, who claimed it was a powerful and benevolent principle for Google and other organizations — corporations in particular.

"Don't be evil" is said to recognize that large corporations can often maximize short-term profits with actions that destroy long-term brand image and competitive position. By instilling a Don't Be Evil culture, the corporation establishes a baseline for decision making that can enhance the trust and image of the corporation that outweighs short-term gains from violating the Don't Be Evil principles.

While many companies have ethical codes to govern their conduct, Google makes "Don't Be Evil" a central pillar of their identity.
