How to Change Your Tumblr Username (Step-by-Step Guide)
By Fred, Editor
Complete guide to changing your Tumblr username and blog URL, including the rules, the redirect window, and how to monitor your dream blog name.
Why Change Your Tumblr Username?
Your Tumblr username is your URL — yourname.tumblr.com — and it's how readers, reblogs, and search results find you. Changing it can help you:
- Rebrand a blog you started years ago
- Claim a cleaner URL as it becomes available
- Match your handle across Tumblr, Bluesky, and Medium
- Move from a fan-blog name to your professional identity
- Make your URL easier to type and share
📋 Step-by-Step: How to Change Your Tumblr Username
- 1
Log into Tumblr
Sign in at tumblr.com with your account.
- 2
Open Settings
Click the account icon in the top-right corner and choose "Settings".
- 3
Select your blog
Choose the blog you want to rename from the left-hand list (each secondary blog has its own URL).
- 4
Edit the URL
Next to the blog URL, click "Edit" and type your new name — Tumblr checks availability as you type.
- 5
Save the change
Click "Save". Your new URL works immediately, and the old one keeps redirecting for a while before being released.
