Independent Baptist churches (some also referred to as
Independent Fundamental Baptist, or IFB) are Christian churches generally holding to conservative Baptist beliefs. They are characterized by being independent from the authority of denominations or similar bodies. Within some denominational churches more conservative elements set about establishing new Independent Baptist churches instead of remaining within the denominational churches.

Independent Baptists remain autonomous and congregationalist in nature and are generally fundamentalist in teaching. The IFB movement is not a denomination
per se, but there are similarities that run throughout most independent Baptist churches. They reject some beliefs and practices found in most denominational churches because of their belief in the doctrine of separation, based on the command "…Come out from among them, and be ye separate, saith the Lord…."(II Corinthians 6:17).
