Rename Your Chromecast in the Google Home App

You change your Chromecast name through the Google Home app, not through your TV or the Chromecast device itself. Open the app on your phone or tablet, find your Chromecast in the list of devices, tap the settings icon (usually three dots or a gear), and select the option to rename. Type the new name you want and save it. The change takes effect when ready.

The name you set here is what appears on your phone when you cast, what shows up on your TV's input list, and what you'll say if you use voice commands with Google Assistant. A clear, specific name like "Living Room TV" or "Kitchen Display" makes it much easier to find the right device when you have multiple Chromecasts at home.

Key Takeaways

  • Open the Google Home app and locate your Chromecast device in the list to access the rename option.
  • Tap the settings icon next to your device name, then select rename and type your new name.
  • The new name appears when ready on your phone, TV, and in voice commands.
  • Descriptive names like "Bedroom TV" or "Patio Speaker" help you identify the right device when casting.
  • You can rename your device as many times as you want with no restrictions or limits.

Step-by-Step Instructions for Android and iPhone

On both Android and iPhone, the process is nearly identical. First, make sure your phone is connected to the same Wi-Fi network as your Chromecast. Open the Google Home app and wait for it to load your device list. You should see your Chromecast listed by its current name.

Tap and hold the device tile, or tap the settings icon (three vertical dots or a gear icon) in the top right corner of the tile. A menu will appear with several options. Look for "Settings," "Device Settings," or "Rename" — the exact wording depends on your app version. Tap that option, and a text field will appear with your current device name highlighted. Delete the old name and type your new one. Tap "Save," "Done," or "Rename" to confirm the change.

If you don't see a rename option in the first menu, try tapping the device tile itself to open the full device page, then look for a settings gear icon at the top of that page. From there, you should find the rename option in the device settings.

What Happens When You Rename Your Device

When you change the name, every place that displays your Chromecast updates automatically. Your phone's cast menu will show the new name within seconds. If you have a Google Home speaker or display in the same home, voice commands will recognize the new name right away — you can say "Hey Google, cast to [new name]" and it will work.

The new name also appears on your TV's input selector if you're using a Chromecast built into a TV or connected to one. If you share your home with other people in the Google Home app, they'll see the new name on their phones too. There's no delay or waiting period — the change is live when ready.

Choosing a Name That Works Well

The best device names describe where the Chromecast is located or what it's connected to. "Living Room TV," "Master Bedroom," "Kitchen Speaker," or "Patio Display" are all clear choices. Avoid names that are too long — they may get cut off in some menus — and avoid special characters like &, %, or @ since some systems don't handle them well.

If you have multiple Chromecasts, numbering them can help: "Bedroom 1," "Bedroom 2," or "TV 1," "TV 2." This makes it obvious which device you're casting to when you're in a hurry. You can always change the name later if you move the device to a different room or want to try a different naming system.

Troubleshooting If the Rename Option Doesn't Appear

If you can't find the rename option, first check that you're signed into the Google Home app with the same Google account that set up the Chromecast. If you're using a different account, you may not have permission to change settings. Sign out and sign back in with the correct account.

Next, make sure your phone and Chromecast are on the same Wi-Fi network. If they're on different networks, the app won't be able to communicate with the device. Restart the Google Home app by closing it completely and opening it again. If the device still doesn't appear or the settings menu is missing, try restarting your Chromecast by unplugging it for 10 seconds, plugging it back in, and waiting for it to fully boot up before opening the app again.

If you're using an older version of the Google Home app, update it from the Google Play Store (Android) or the App Store (iPhone). Older versions sometimes have missing features or display bugs that prevent the rename option from showing up.

Renaming a Chromecast Built Into Your TV

If your TV has Chromecast built in, the process is identical — you still use the Google Home app on your phone. The TV itself doesn't need to be on, though it's easier to confirm the change worked if you turn it on. Set up the built-in Chromecast through the Google Home app the same way you would a standalone device, and then rename it using the same steps.

Built-in Chromecasts sometimes come with generic names like "Living Room TV" or "Bedroom TV" already assigned by the manufacturer. You can change these to anything you want. The new name will appear on your phone's cast menu and on the TV's input list.

Frequently Asked Questions

Can I rename my Chromecast from the TV remote or the device itself?

No. Chromecast devices don't have a menu system on the device itself, and the TV remote won't control Chromecast settings. You must use the Google Home app on your phone or tablet to rename your device. This is the only way to change the name.

Will renaming my Chromecast affect my casting or saved shows?

No. Renaming only changes the label that appears in menus and voice commands. Your casting history, saved content, and all settings remain exactly the same. You can rename your device as many times as you want without losing anything.

What if I have multiple Chromecasts and I'm not sure which one is which?

Open the Google Home app and tap each device one at a time. When you tap a Chromecast, it will briefly display a color animation or notification on the TV it's connected to. This helps you identify which physical device matches which name in the app. Once you know which is which, you can rename them to match their locations.

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

The Google Home app will let you type emoji, but some systems and voice commands may not display or recognize them correctly. Stick to letters, numbers, and basic punctuation like hyphens or underscores for the most reliable results across all your devices.

Do I need to rename my Chromecast if I move it to a different room?

You don't have to, but it's a good idea. Renaming it to match its new location makes it much easier to find when you're casting from your phone or using voice commands. It takes only a few seconds and prevents confusion later.
