# Deleting a subnet group
<a name="subnetgroups.deleting"></a>

If you decide that you no longer need your subnet group, you can delete it. You cannot delete a subnet group if it is currently in use by a cluster. You also cannot delete a subnet group on a cluster with Multi-AZ enabled if doing so leaves that cluster with fewer than two subnets. You must first uncheck **Multi-AZ** and then delete the subnet.

The following procedures show you how to delete a subnet group.

<a name="subnetgroups.deleting.api"></a>

Using the MemoryDB API, call `DeleteSubnetGroup` with the following parameter:
+ `SubnetGroupName=mysubnetgroup`

**Example**  

```
https://memory-db.us-east-1.amazonaws.com/
    ?Action=DeleteSubnetGroup
    &SubnetGroupName=mysubnetgroup
    &SignatureMethod=HmacSHA256
    &SignatureVersion=4
    &Timestamp=20210801T220302Z
    &Version=2021-01-01
    &X-Amz-Algorithm=Amazon4-HMAC-SHA256
    &X-Amz-Credential=<credential>
    &X-Amz-Date=20210801T220302Z
    &X-Amz-Expires=20210801T220302Z
    &X-Amz-Signature=<signature>
    &X-Amz-SignedHeaders=Host
```
