The new apps -- for Apple TV, Amazon's Fire TV and Samsung Smart TV -- will provide a more convenient way for users of the social network to view videos on a large screen.
The move could be a small step toward what some reports say is a more ambitious video plan by Facebook to compete with Google-owned YouTube or even with streaming services such as Netflix.
For now, the apps will simply make it easier to view and share user-generated video.
"With the app, you can watch videos shared by friends or pages you follow, top live videos from around the world, and recommended videos based on your interests."
Facebook said it expects the applications to roll our "soon" for users of Apple, Amazon and Samsung, with additional platforms likely to be added.
Facebook also said it was modifying video playback for users, with sound to play automatically unless users silence their devices.
