How can I delete a remote branch in a local git repository?

All the remote branches are visible as remotes in my local git repository after a git fetch.

How to selectively remove the remote branches in my local repository (not in the remote repository)?

I had a slightly different but similar issue, but the solution might be useful to others who stumble on this question...

I noticed that my local repository still had remote branches that no longer existed on the remote, so I wanted to remove them. The solution is simply to fetch with the --prune (or -p) option:

git fetch --prune

git branch -r -d remote/branch

You also need to reconfigure fetch to avoid fetching this branch again later
