+# google_access_context_manager_access_policy
+
+Get information about an Access Context Manager AccessPolicy.
+
+## Example Usage
+
+```tf
+data "google_access_context_manager_access_policy" "policy-org" {
+  parent       = "organizations/1234567"
+}
+
+data "google_access_context_manager_access_policy" "policy-scoped" {
+  parent       = "organizations/1234567"
+  scopes       = ["projects/1234567"]
+}
+
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `parent` - (Required) The parent of this AccessPolicy in the Cloud Resource Hierarchy. Format: `organizations/{{organization_id}}`
+
+* `scopes` - (Optional) Folder or project on which this policy is applicable. Format: `folders/{{folder_id}}` or `projects/{{project_number}}`
+
+
+## Attributes Reference

+In addition to the arguments listed above, the following attributes are exported:
+
+* `name` - Resource name of the AccessPolicy.
+
+* `title` - Human readable title. Does not affect behavior.
