The World Evangelical Alliance (WEA) is a network of churches in 129 nations and over 100 international non-governmental organizations joining together to provide a world-wide identity, voice, and platform to more than 600 million evangelical Christians.

The WEA is a unification based on the historic Christian faith expressed in the evangelical tradition. The WEA is a global association of national and regional Alliances, global networks, partners and associated ministries who work together to strengthen the evangelical Church around the world to advance the Good News of Jesus Christ and to seek holiness, justice and renewal at every level of society, so that God is glorified as the nations of the earth are transformed.

The WEA's activities are centered on three pillars: (1) represent with a global voice, (2) equip for global impact, (3) connect for common action.
