+ Allows management of the entire IAM policy for a Google Cloud Platform Organization.
+---
+
+# google\_organization\_iam\_policy
+
+Allows management of the entire IAM policy for an existing Google Cloud Platform Organization.
+
+~> **Warning:** New organizations have several default policies which will,
+   without extreme caution, be **overwritten** by use of this resource.
+   The safest alternative is to use multiple `google_organization_iam_binding`
+   resources.  It is easy to use this resource to remove your own access to
+   an organization, which will require a call to Google Support to have
+   fixed, and can take multiple days to resolve.
+
+~> **Note:** This resource __must not__ be used in conjunction with
+   `google_organization_iam_member` or `google_organization_iam_binding`
+   or they will fight over what your policy should be.
+
+## Example Usage
+
+```hcl
+resource "google_organization_iam_policy" "policy" {
+  org_id = "123456789"
+  policy_data = "${data.google_iam_policy.admin.policy_data}"
+}
+
+data "google_iam_policy" "admin" {
+  binding {
+    role = "roles/editor"
+
+    members = [
+      "user:[email protected]",
+    ]
+  }
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `org_id` - (Required) The numeric ID of the organization in which you want to create a custom role.
+
+* `policy_data` - (Required) The `google_iam_policy` data source that represents
+    the IAM policy that will be applied to the organization. This policy overrides any existing
+    policy applied to the organization.
+
+## Import
+
+```
+$ terraform import google_organization_iam_policy.my_org your-org-id
+```
