+  Get information about a Policy Definition.
+---
+
+# Data Source: azurerm_policy_definition
+
+Use this data source to access information about a Policy Definition, both custom and built in. Retrieves Policy Definitions from your current subscription by default.
+
+## Example Usage
+
+```hcl
+data "azurerm_policy_definition" "test" {
+  display_name = "Allowed resource types"
+}
+
+output "id" {
+  value = "${data.azurerm_policy_definition.test.id}"
+}
+```
+
+## Argument Reference
+
+* `display_name` - (Required) Specifies the name of the Policy Definition.
+* `management_group_id` - (Optional) Only retrieve Policy Definitions from this Management Group.
+
+
+## Attributes Reference
+
+* `id` - The ID of the Policy Definition.
+* `name` - The Name of the Policy Definition.
+* `type` - The Type of Policy.
+* `description` - The Description of the Policy.
+* `policy_type` - The Type of the Policy, such as `Microsoft.Authorization/policyDefinitions`.
+* `policy_rule` - The Rule as defined (in JSON) in the Policy.
+* `parameters` - Any Parameters defined in the Policy.
+* `metadata` - Any Metadata defined in the Policy.
