You use the deregister() API.

There are a few ways of getting the image id (i.e. you can list all images and search their properties, etc)

Here is a code fragment which will delete one of your existing AMIs (assuming it’s in the EU region)

connection = boto.ec2.connect_to_region('eu-west-1', 
                                    aws_access_key_id='yourkey', 
                                    aws_secret_access_key='yoursecret', 
                                    proxy=yourProxy, 
                                    proxy_port=yourProxyPort)


# This is a way of fetching the image object for an AMI, when you know the AMI id
# Since we specify a single image (using the AMI id) we get a list containing a single image
# You could add error checking and so forth ... but you get the idea
images = connection.get_all_images(image_ids=['ami-cf86xxxx'])
images[0].deregister()

(edit): and in fact having looked at the online documentation for 2.0, there is another way.

Having determined the image ID, you can use the deregister_image(image_id) method of boto.ec2.connection … which amounts to the same thing I guess.

With newer boto (Tested with 2.38.0), you can run:

ec2_conn = boto.ec2.connect_to_region('xx-xxxx-x')
ec2_conn.deregister_image('ami-xxxxxxx')

or

ec2_conn.deregister_image('ami-xxxxxxx', delete_snapshot=True)

The first will delete the AMI, the second will also delete the attached EBS snapshot

For Boto2, see katriels answer. Here, I am assuming you are using Boto3.

If you have the AMI (an object of class boto3.resources.factory.ec2.Image), you can call its deregister function. For example, to delete an AMI with a given ID, you can use:

import boto3

ec2 = boto3.resource('ec2')

ami_id = 'ami-1b932174'
ami = list(ec2.images.filter(ImageIds=[ami_id]).all())[0]

ami.deregister(DryRun=True)

If you have the necessary permissions, you should see an Request would have succeeded, but DryRun flag is set exception. To get rid of the example, leave out DryRun and use:

ami.deregister() # WARNING: This will really delete the AMI

This blog post elaborates on how to delete AMIs and snapshots with Boto3.

Script delates the AMI and associated Snapshots with it. Make sure you have right privileges to run this script.

Inputs – Please pass region and AMI ids(n) as inputs

import boto3
import sys

def main(region,images):
    region = sys.argv[1]
    images = sys.argv[2].split(',') 
    ec2 = boto3.client('ec2', region_name=region)
    snapshots = ec2.describe_snapshots(MaxResults=1000,OwnerIds=['self'])['Snapshots']
        # loop through list of image IDs
    for image in images:
        print("====================nderegistering {image}n====================".format(image=image))
        amiResponse = ec2.deregister_image(DryRun=True,ImageId=image)
        for snapshot in snapshots:
            if snapshot['Description'].find(image) > 0:
                snap = ec2.delete_snapshot(SnapshotId=snapshot['SnapshotId'],DryRun=True)
                print("Deleting snapshot {snapshot} n".format(snapshot=snapshot['SnapshotId']))
    
main(region,images)

using the EC2.Image resource you can simply call deregister():

Example:

for i in ec2res.images.filter(Owners=['self']):
    print("Name: {}t Id: {}tState: {}n".format(i.name, i.id, i.state))
    i.deregister()

See this for using different filters:
