+
+# Data Source: azurerm_eventgrid_domain_topic
+
+Use this data source to access information about an existing EventGrid Domain Topic
+
+## Example Usage
+
+```hcl
+data "azurerm_eventgrid_domain_topic" "example" {
+  name                = "my-eventgrid-domain-topic"
+  resource_group_name = "example-resources"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - The name of the EventGrid Domain Topic resource.
+
+* `domain_name` - The name of the EventGrid Domain Topic domain.
+
+* `resource_group_name` - The name of the resource group in which the EventGrid Domain Topic exists.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The EventGrid Domain Topic ID.
+
+* `domain_name` - The EventGrid Domain Topic Domain name.
+
+## Timeouts
+
+The `timeouts` block allows you to specify [timeouts](https://www.terraform.io/docs/configuration/resources.html#timeouts) for certain actions:
+
+* `read` - (Defaults to 5 minutes) Used when retrieving the EventGrid Domain Topic.
