Change Your Chromecast Name in the Google Home App

You rename a Chromecast through the Google Home app on your phone or tablet, not on the device itself. Open the Google Home app, find your Chromecast in the list of devices, tap the settings icon (three dots or a gear), and select "Device settings." From there, tap the device name at the top and type a new one. The change takes effect when ready.

The process is the same whether you have a Chromecast Audio, Chromecast with Google TV, or an older Chromecast dongle. You need to be signed into the same Google account that set up the device, and your phone must be on the same Wi-Fi network as the Chromecast.

Key Takeaways

  • Open the Google Home app, tap your Chromecast device, then tap the settings icon (three dots or gear) to reach device settings.
  • Tap the device name at the top of the settings screen and type your new name directly into the text field.
  • New names take effect right away and show up on all your devices that cast to that Chromecast.
  • You must be signed into the same Google account that originally set up the Chromecast to change its name.

Step-by-Step Instructions for Android and iPhone

On Android: Open Google Home. Long-press the Chromecast device tile, or tap the three-dot menu icon on the tile. Select "Device settings." Tap the device name at the top of the screen. Clear the current name and type the new one. Tap the checkmark or press Enter to save.

On iPhone or iPad: Open Google Home. Tap and hold the Chromecast device tile until a menu appears. Tap the settings icon (gear). Tap the device name at the top. Delete the old name and type the new one. Tap "Done" or press the keyboard's return button to save.

If you do not see the device in Google Home, make sure your phone is connected to the same Wi-Fi network as the Chromecast. If the Chromecast is offline or not responding, restart it by unplugging it for 30 seconds, then plugging it back in.

What Happens After You Rename Your Device

The new name appears in Google Home within seconds. When you cast from another device—a phone, tablet, or computer—the Chromecast will show up under its new name in the cast menu. If you have multiple Chromecasts in your home, a clear name like "Living Room TV" or "Kitchen Speaker" makes it much easier to pick the right one when casting.

The name change does not affect any of your casting history, saved preferences, or connected accounts. If you rename the device again later, all your settings stay the same.

Renaming a Chromecast You Do Not Own

You can only rename a Chromecast if you have access to the Google Home app and are signed into the account that set it up. If someone else in your household set up the device, ask them to change the name, or ask them to give you permission to manage the device in Google Home.

If you are trying to rename a Chromecast at work or in a shared space, the person who set it up must do it, or they must add your account as a manager in the device settings first.

Common Mistakes to Avoid

Do not try to rename the Chromecast by changing the Wi-Fi network name or your Google account name—neither of these affects the device name. The device name lives only in Google Home and is separate from everything else.

If you type a name and it does not save, make sure you tapped the checkmark, pressed Enter, or tapped "Done" before leaving the screen. If the app closes without saving, open Google Home again and try once more. If the device is offline, it will not accept name changes until it reconnects to Wi-Fi.

Avoid using special characters or very long names. Stick to letters, numbers, spaces, and hyphens. Names longer than 30 characters may not display properly on some devices.

Renaming Multiple Chromecasts at Once

If you have several Chromecasts in different rooms, rename each one individually through Google Home. There is no bulk rename feature. However, once you name them clearly—such as "Bedroom," "Living Room," and "Kitchen"—Google Home will remember these names and display them consistently across all your devices.

A good naming system saves time when casting. Use room names, device types (like "TV" or "Speaker"), or both. Avoid generic names like "Chromecast 1" or "Device," which make it hard to remember which one is which.

Frequently Asked Questions

Can I rename my Chromecast from a computer instead of a phone?

Yes. Go to home.google.com in a web browser, sign in with the same Google account, find your Chromecast, click the settings icon, and click the device name to edit it. The process is the same as on the mobile app.

What if I forgot which Google account set up my Chromecast?

Try signing into Google Home with each account you use. The Chromecast will appear only under the account that set it up. Once you find the right account, you can rename it. If you no longer have access to that account, you may need to factory reset the Chromecast and set it up again.

Does renaming my Chromecast change my Wi-Fi network name?

No. The device name and the Wi-Fi network name are completely separate. Renaming your Chromecast in Google Home does not affect your Wi-Fi at all.

Can I use emoji or special characters in the device name?

Google Home accepts most letters and numbers, but special characters and emoji may not display correctly on all devices. Stick to letters, numbers, spaces, and hyphens for the most reliable result.

Why does my new Chromecast name not show up when I cast?

Close the casting app completely and reopen it. The cast menu sometimes needs to refresh to show the new name. If it still does not appear, restart your phone and the Chromecast by unplugging it for 30 seconds.
