There was a time when you could download a Facebook app to your Roku device to view Facebook on a TV. That app is no longer available, and nothing has replaced it, so it's not technically possible to get Facebook or Facebook Live on your Roku.
However, there are a few alternatives like screen mirroring, using a different service or streaming device, connecting your smartphone or computer to your TV using a wired connection, or trying your Smart TV's browser.
Get Facebook on Roku with Screen Mirroring
One thing you can do is to screen mirror Facebook from your mobile phone or tablet. While this isn't strictly the Facebook app for Roku, the result is the same. You can browse your profile or watch Facebook Live or Facebook Watch on your television.
Make sure your Roku device is correctly connected to your TV. If you're not sure or setting Roku up for the first time, read our article about setting up your Roku.
Once your Roku is working, make sure to connect your mobile phone and Roku to the same W-Fi network. Then make sure your Roku is on the home screen.
Using the Roku remote, scroll down and select Settings at the bottom of the left-hand navigation menu.
Then choose System.
Select Screen Mirroring and choose Prompt, Always allow, or Never allow. In this case, either Prompt or Always allow will work.
If you plan to screen mirror to your Roku often, select Always allow so you don't have to go through these steps every time you want to screen mirror from your device to your TV.
Give your Roku a few minutes to search for your mobile device. Once you see it on the Allowed devices menu on the right side of the screen, select the device.
Launch the Facebook app on your mobile device, and it should display on your TV.
You'll still have to control Facebook from your phone, but at least you'll have the larger screen of your TV for viewing Live or Watch content.
