+# Show Tables That Match A Pattern
+
+An unfamiliar database with tons of tables can be a difficult thing to
+navigate. You may have an idea of the kind of table you are looking for
+based on a domain concept you've seen elsewhere.
+
+You can pare down the results returned by `show tables` by including a
+`like` clause with a pattern. For example, this statement will show me only
+tables that have the word `user` in them:
+
+```sql
+> show tables like '%user%';
++-------------------------------+
+| Tables_in_jbranchaud (%user%) |
++-------------------------------+
+| admin_users                   |
+| users                         |
++-------------------------------+
+```
