+# DROP INDEX
+
+```ngql
+DROP {TAG | EDGE} INDEX [IF EXISTS] <index_name>
+```
+
+The `DROP INDEX` statement drops an existing index from the current graph space. Dropping a nonexistent index results in an error. You can use the `IF EXISTS` option to conditionally drop the index and avoid the error. To run this statement you need some privilege. For information about the built-in roles in Nebula Graph, see [Built-in roles](TODO) (TODO).
+
+## Example
+
+```ngql
+nebula> DROP TAG INDEX player_index_0;
+```
+
+This query drops a tag index names `player_index_0`.
