There is no *direct* way to get it, but you can get to it with a bit of data analysis. The process is:
The person who did that is the person who added your label. (Assuming no-one has issue deleted permission - that would mean you've destroyed the record completely)
@Gursoy Yerli there is not a way to do that. There are a few apps that provide additional label functionality but I do not think that is one of them - https://marketplace.atlassian.com/search?application=jira&hosting=cloud&product=jira&q=label&query=labels
I was also not able to find a feature request like that here: https://jira.atlassian.com/secure/Dashboard.jspa You can raise one and vote for it.
