Rename Your Chromecast in the Google Home App

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

If you have multiple Chromecasts in your home, renaming them to match their location (like "Living Room TV" or "Kitchen Speaker") makes it much easier to control the right device when you're casting. You can change the name as many times as you want without affecting how the device works.

Key Takeaways

  • Open the Google Home app, find your Chromecast, tap the settings icon, and select the rename option to change the device name in seconds.
  • Device names can be up to 32 characters long and update when ready across all your devices once you save the change.
  • Renaming a Chromecast does not affect its settings, casting ability, or network connection — it only changes what the device is called.
  • If you cannot find the settings icon in Google Home, make sure you are tapping and holding the device tile, not just tapping it once.

Step-by-Step Instructions for Android and iPhone

On Android: Open Google Home, locate your Chromecast device, and tap and hold the device tile until a menu appears. Tap the settings icon (gear or three dots) in the top right corner. Select "Device settings," then tap the device name at the top of the screen. Clear the current name, type the new one, and tap the checkmark or "Save" button.

On iPhone or iPad: The process is identical. Open Google Home, find your Chromecast, tap and hold the device tile, select the settings icon, choose "Device settings," tap the name field, and enter your new name. Save the change and you are done.

If the settings icon does not appear when you tap and hold, try tapping the device tile once to open its detail page, then look for a settings or gear icon in the top right corner of that page. Some versions of Google Home place the settings option in slightly different locations depending on your app version.

Renaming Through a Computer Browser

You can also rename your Chromecast using a web browser on a computer. Go to myaccount.google.com/device-activity or home.google.com (if you have Google Home set up on the web). Sign in with the same Google account linked to your Chromecast. Find your device in the list, click on it, and look for a settings or edit option. Click the device name to edit it, type the new name, and save.

This method works if you prefer using a keyboard and larger screen, or if you are having trouble with the mobile app. The change syncs across all your devices within a few seconds.

What Happens When You Rename a Chromecast

Renaming your Chromecast changes only the display name — the label you see in the Google Home app and on your phone or tablet when you cast. The device's internal settings, network connection, and casting functionality remain unchanged. You will not lose any saved preferences, Wi-Fi passwords, or linked accounts.

The new name appears on all devices connected to your Google account within moments. If you have family members or guests using the same Chromecast, they will see the new name in their Google Home app as well. The name does not affect which apps can cast to the device or how it performs.

Troubleshooting If the Name Will Not Change

If you enter a new name but it reverts to the old one, make sure you are fully saving the change — look for a "Save," checkmark, or "Done" button and tap it before leaving the screen. If the app closes before you save, the change will not stick.

If the Google Home app is not showing your Chromecast at all, check that your phone and the Chromecast are on the same Wi-Fi network. Restart the Google Home app by closing it completely and opening it again. If your Chromecast is offline (shown as grayed out in the app), turn it off and back on, wait 30 seconds, and try renaming it again once it reconnects.

For older Chromecast models or if you are using a different casting device (like a Chromecast Audio or Chromecast with Google TV), the steps are the same — open Google Home, find the device, and access its settings to rename it.

Naming Tips for Multiple Devices

If you have several Chromecasts in your home, use names that describe where each one is located or what it is connected to. Examples include "Living Room TV," "Bedroom Speaker," "Kitchen Display," or "Office Monitor." Avoid names with special characters or very long strings, as they can be harder to read in the app or on your phone's casting menu.

You can also use names that describe the device type if you prefer — "TV Chromecast," "Audio Chromecast," or "Google TV." The key is choosing something you will recognize when ready when you are casting, so you do not accidentally send music to your TV or a video to your speaker.

Frequently Asked Questions

Can I change my Chromecast name without the Google Home app?

Yes. You can rename it through a web browser at home.google.com or myaccount.google.com/device-activity using the same Google account. The mobile app is faster, but the web method works if you prefer a computer.

Will changing the name affect my casting or Wi-Fi connection?

No. Renaming only changes the label you see in the app. Your Chromecast will work exactly the same way, stay on the same network, and keep all its settings and linked accounts.

What if I forget what I named my Chromecast?

Open the Google Home app and look at the device list — the current name is displayed there. You can also check your Google account settings at myaccount.google.com to see all your linked devices and their names.

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

Most special characters and emojis will work, but keep the name under 32 characters and avoid very long strings. Stick to letters, numbers, spaces, and common punctuation for the clearest display across all your devices.

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

The name change takes effect when ready in the Google Home app and on your casting menu. If you have multiple devices or family members using the same account, the new name will sync within a few seconds.
