Change Default branch in gitlab

Question

in the GitLab Enterprise Edition 12.2.0-pre you have to use following: Setting → Repository → Default Branch ( expand it) and change the default branch Here

In 8.0+ it looks like this was moved into the project. If you open your project and go to the gear icon on the right, then "Edit Project" you can set the default branch for the project.

To change default branch in GitLab:
1. Settings > General > General project settings > Expand
2. Default Branch > Change your project default branch
3. Save changes

For gitlab v10+ (as of Sept 2018), this has moved to settings-> repository -> default branch

As stated by @Luke this is still valid as on 4/1/2021

To change the default branch in Gitlab 7.7.2:

• Click Settings in the left-hand bar
• Change the Default Branch to the desired branch
• Click Save Changes.

1. Settings
2. General
3. General Project Settings

In the latest GitLab Community Edition version 9.2.2.:

1. You have to click on 'Settings' tab located at right most on tabs panel after opening the project.
2. Under 'Settings' you will get section 'Default Branch' dropdown which will give you all branches for the repository. Select the desired branch.
3. Scroll down to hit green colored 'Save changes' button located just after 'Project Avatar'.
