The first update to its mission statement since the end of the Cold War in 1991 gives Nato a broader role than just defending its own borders.
It allows for intervention beyond its territory to halt regional crises and to meet other threats to its members' security.
The initiative also aims to make Nato forces more mobile and increase the accuracy of their weapons systems.
BBC Political Correspondent Jon Sopel says Nato is seeking to become a leaner and meaner fighting force, moving away from its original conception as a defensive organisation.
US President Bill Clinton said the alliance could now "advance security and freedom for another 50 years".
He said the new role would include:
Security guarantee

Nato Secretary-General Javier Solana said a stronger alliance had been created, which would guarantee security in Europe and uphold democratic values.
He welcomed the membership of Hungary, Poland and the Czech Republic, saying enlargement of the alliance remained a priority.
"Nato is committed to keep its door open. The three new members which have celebrated here will not be the last," he said.
French praise
The Nato agreement also stressed the "primary responsibility" of the United Nations Security Council for world peace, without giving it an explicit veto on Nato action.
French President Jacques Chirac hailed this, saying it meant "Nato cannot and will not be able to act without the authorisation of this international organisation".
After overcoming Turkish objections, leaders also approved a statement recognising the European Union's role in security and defence policy and its right to approve military action where the alliance as a whole was not engaged.
