Take a look at How to delete labels in JIRA applications:
Note that in JIRA server applications, labels can only be replaced, rather than added or removed. See JRASERVER-24118 - The labels fields should be additive when doing bulk updates Closed for progress on this feature
You can make it so the labels no longer show up when browsing project labels:
To completely delete a label from a JIRA application project, the label must be removed from all the issues in that project. Once it is removed from all issues, it will no longer be seen when browsing a project's labels.
How do I find which labels are in my projects?
See Labeling an Issue.
How do I bulk-remove a label?
Both cloud and server application users can also watch the following feature request for improved label management in JIRA applications: JRASERVER-33672 - Improve the way Labels can be deleted in JIRA.
If you have many labels that you want to manage or delete, removing from each issue will be very time consuming.
For that use case, you can use our app: Label Manager for Jira Cloud
It allows managing labels (searching, filtering, changing name, deleting etc.) from a single page. Try it out and let us know if you face any issues.
Thank you for this app - very useful and did exactly what we needed.
We had hundreds of labels across multiple projects, and wanted to delete ALL of these, as the purpose they had previously served was no longer relevant, and we wanted to start over with a fresh set of labels.
By using this app, we just needed to go to the project wide labels list and click 'Delete' next to each one we no longer required. The app did the rest - updating each ticket to remove the labels.
Now when we go to add a label on a new ticket, we are only shown the list we now want to see, rather than these old, redundant labels.
Massive time saver. Thank you.
Doesn't work for me either. I've deleted around 5 labels that I've created, and no one else probably used them. I'm a Jira administrator, so the changes of having some issues with these labels that I don't have access are close to zero.
I've logged out and the problem persists.
