I'm currently busy with a project with a lot of branches and I have a tag for last changes which where done on one of the branches. But it's not clear for me on which branch this tag is.
How to find out on which branch a tag is?

Even shorter:
git branch --contains tags/<tag> (it works for any tree-ish reference)
If you can find which commit a tag refers to:
git rev-parse --verify tags/<tag>^{commit} # or, shorter: git rev-parse tags/<tag>~0 Then you can find which branch contain that commit.
git branch --contains <commit> As commented below by user3356885, for the fetched branches (branches in remotes namespace)
git branch -a --contains tags/<tag> git branch -a --contains <commit> As noted in Pyr3z's answer, for each candidate tag listed above, you can add:
git log -1 --pretty='%D' TAG That will show the branches associated to that tag.

On my version of Git, 1.7.1, I can simply do
git branch --contains <tag>.

Looking for tag that was created on remote branch won't produce any results in this case. Another words, no results will be produced for branches that do not exist locally. Option -a should be used for that.
git branch -a --contains <tag>. Same will work for commits.

Unfortunately this returns multiple things: * (HEAD detached at 82dd3f0) master refs/tags/0.0.1-test-masterBr --> I want to programatically access the branch, no HEAD info or the tag itself

git branch --contains <tag>. git version 2.23.0, zsh, open SUSE tumbleweed. I do not think this is specific to my OS or shell, I think this is the default thing modern git versions do. They open a list in a pager

@tzg Yes, without the tag, I do see the branch... but the all idea was to get the branch where the tag is.

If "git branch --contains " does nothing, be sure that you are including all branches, both remote and local branches:
git branch -a --contains <tag> From the git help:
Specific git-branch actions: -a, --all list both remote-tracking and local branches

What if the branch is deleted and pruned? e.g., a beta tag?
My problem with the top answers here—
—specifically solutions like
git branch -a --contains TAG and similar had the problem of being able to list multiple branches in the output, and it isn't clear which is the one the tag ACTUALLY originated in:
$ git branch --contains TAG branch-A branch-B * branch-C branch-D (the * marks the current branch = not relevant)
Oh, and sorting with --sort=-committerdate or =-taggerdate doesn't exactly clarify the original branch, since these ref attributes can be updated by actions not related to the TAG in question.
git show TAG
DID give me the true answer to my question ("which branch was this tag created on?"), however the git show format is quite bulky by default, and what I was looking for was an efficient, machine-friendly output format in order to pass to some automated scripts.
So turns out, git log is the core command for the job:
git log -1 --format='%D' TAG This gives output like:
tag: TAG, origin/branch-B, branch-B Which tells us exactly the branch the tag originated on, and is much more machine-readable.

git log doesn’t show branch for me… not sure why
LyrePyre
@Shmidt there could be a variety of reasons why that is... Do any branches show for you when you run a plain
git log?

Any way to get the output of git log to show just "branch-B"?
LyrePyre
@tzg I think this would answer your question?
git log -1 --format='%D' TAG | grep -Eo '[^ ]+$' Not 100% certain, worked in my tests but it assumes that the branch name you're after is always listed last.

@Shmidt the problem with the git log approach is that you only see the branch, if the tag corresponds to the latest commit on that branch. If the tag is in some earlier commit, git log will show you the tag in parantheses after the commit, but not the branch name (since the branch name is just an alias for the HEAD commit in that branch). That means with git log you will not be able to get the branch for tags that were set in some earlier commits of a branch.

In regards to @VonC's comment about finding the commit referenced by a tag, just use:
git show <tag> Since a tag is tied to a specific commit, it can be used to show that commit - which will give you the full commit details.

git branch --contains tag does nothing for me, but I found my solution to this problem in git gui.
Start it like this:
git gui (On my Ubuntu I had to install it first with sudo apt-get install git-gui.)
Then I selected the menu item Repository -> Visualize All Branch History. In the resulting window I then selected the menu item File -> List References.
Another window popped up, listing all my tags (and other references). These are clickable and after clicking one of them I just had to check the bottom left frame for the list of branches. Like this:
Parent: somesha (message) Parent: someothersha (another message) Child: anothersha (yet another message) Branches: branch1, master, remotes/origin/branch2, remotes/upstream/branch1, etc Follows: v1.1.2 Precedes: v1.1.4

You can also try this , had similar use case and this worked for me
git ls-remote --heads origin | grep $CI_COMMIT_SHORT_SHA | sed "s/.*\///" Slightly different but taking inspiration from @ttfreeman's answer

With a Tag you mark a reference. So when you are on a dev branch and Tag this state. Your tag is on the actual reference. So in this case you can look to gitk or another tool where the tree is shown. There you can see on which reference the Tag is.
git: Is there something like per-branch tags?
http://git-scm.com/book/en/Git-Basics-Tagging
Here is a good explanation.

A tag is always referring to commit number. Using that tag number you can find the branch from which the tag was placed using this:
git for-each-ref | grep ${commit_num} | grep origin | sed "s/.*\///"

Step 1. Get commit id:
git show {tag name} Step 2. Copy commit id and paste to get all branches:
By example: git branch --contains 94a152c2d1c6830c5a044ecf20526d51e64bda83
