Change Your Chromecast Name in the Google Home App

The fastest way to rename your Chromecast is through the Google Home app, which you can read on any phone or tablet. Open the app, find your Chromecast in the device list, tap the settings icon (usually three dots or a gear), and select "Device name" or "Rename." Type the new name you want—up to 32 characters—and save. The change takes effect when ready.

If you have multiple Chromecasts in your home, this method is especially useful because you can see all your devices at once and rename them without switching between screens. The app works on both Android and iOS, so the steps are nearly identical regardless of which phone you use.

Key Takeaways

  • Your Chromecast name can be up to 32 characters long and can include letters, numbers, and most punctuation marks.
  • If the Google Home app does not show your Chromecast, make sure your phone and device are on the same Wi-Fi network.
  • You can rename your Chromecast from any phone or tablet that has the Google Home app installed and is connected to your home network.
  • The new name appears when ready on all your devices and in voice commands—you can say "Hey Google, play music on [new name]" right away.

What to Do If Your Chromecast Does Not Appear in Google Home

Sometimes the Google Home app does not show your Chromecast even though it is plugged in and powered on. The most common reason is that your phone and Chromecast are on different Wi-Fi networks. Check that both devices are connected to the same network—look at your phone's Wi-Fi settings and make sure the Chromecast is on the same one.

If they are on the same network and the device still does not appear, try unplugging the Chromecast for 30 seconds, then plug it back in and wait two minutes for it to fully restart. Open Google Home again and refresh by swiping down from the top of the screen. If it still does not show up, you may need to set up the Chromecast again using the initial setup process.

Renaming Your Chromecast During Initial Setup

When you first set up a new Chromecast, Google Home asks you to name it before the setup is complete. You can give it a descriptive name at that point—for example, "Living Room TV" or "Bedroom Chromecast"—rather than accepting the default name. This saves you a step later.

If you skipped naming it during setup or accepted the default, you can always change it afterward using the method described in the first section. There is no penalty for renaming a device multiple times, so feel free to change it whenever you want.

Naming Tips That Make Voice Commands Easier

Choose a name that is straightforward to say out loud, since you may use voice commands to control your Chromecast. Names like "Living Room," "Kitchen," or "Bedroom" work better than "Chromecast 1" or "Device A" because they are faster to say and less likely to be misheard by Google Assistant.

Avoid names with special characters or numbers that are hard to pronounce. For example, "TV-2B" might be misheard as "TV to B" or "TV dash two B." Stick to straightforward words and short phrases. If you have multiple Chromecasts, naming them by room makes it obvious which one you are controlling when you give a voice command.

Changing the Name on Older Chromecast Models

Older Chromecast devices (first and second generation) use the same Google Home app to rename, so the process is identical to newer models. Open Google Home, find your device, tap settings, and select rename. The only difference is that very old devices may take slightly longer to update the name across your network.

If you have a Chromecast Audio or Chromecast with Google TV, the steps are also the same—all Chromecast products rename through the Google Home app. The app automatically detects which type of device you have and shows the correct settings.

What Happens to Your Casting History When You Rename

Renaming your Chromecast does not erase any casting history, saved apps, or settings. Your device keeps all its data and preferences. The only thing that changes is the name that appears in the Google Home app and in voice commands. If you have cast shows, music, or photos to that Chromecast before, those actions remain in your Google account history.

If you ever want to revert to the original name, you can rename it back at any time using the same method. Google does not lock you into a name choice.

Frequently Asked Questions

Can I use special characters or emojis in my Chromecast name?

Most special characters work, but emojis do not display correctly on all devices. Stick to letters, numbers, spaces, hyphens, and underscores for the most reliable results. Names like "Living-Room TV" or "Kitchen_Chromecast" work fine.

Will renaming my Chromecast affect casting from my phone or computer?

No. Casting works the same way regardless of the device name. The name only changes how the device appears in the Google Home app and how you refer to it in voice commands. All your casting apps will continue to work normally.

What if I forget what I named my Chromecast?

Open the Google Home app and look at the device list—your Chromecast name appears there. You can also say "Hey Google, show me my devices" and Google Assistant will list all your Chromecasts by name. If you want to change it, just follow the rename steps again.

Can multiple people in my home rename the same Chromecast?

Yes. Anyone with access to the Google Home app on your home network can rename any Chromecast. There is no lock or permission system for renaming, so any family member can change the name at any time. If you want to prevent accidental changes, you would need to restrict who has access to the Google Home app itself.

How long does it take for the new name to show up everywhere?

The name change appears in the Google Home app within a few seconds. Voice commands recognize the new name when ready. If you are casting from other apps or devices, they may take up to a minute to refresh and show the new name, but casting functionality is not affected during that time.
