Resident Aliens: Life in the Christian Colony is a 1989 book authored by the theologians Stanley Hauerwas and William Willimon.

It argues that churches should focus on developing Christian life and community rather than attempting to reform secular culture.

Hauerwas and Willimon reject the idea that America or any other country is a Christian nation, instead believing that Christians should see themselves as "resident aliens" in a foreign land, using the metaphor of a colony to describe the church.

Hauerwas and Willimon proceed to discuss ethics and the relationship between Christianity and politics, critiquing the notion that Christians, or the church as a whole, should attempt to transform secular governments or get overly involved in politics in an attempt to change society.
