YouTube is a global online video platform you can access on the web at youtube.com or through the official YouTube app on phones, tablets, smart TVs, and many other devices.

Where YouTube “is” (physically)

If you mean “where is YouTube located in real life?”:

  • Its main headquarters is in San Bruno, California, USA, at 901 Cherry Avenue.
  • It also uses nearby buildings on Cherry Avenue in San Bruno as part of its campus.
  • YouTube has important offices in other cities, like Los Angeles (for entertainment and creators) and London (for European operations).

So in the physical world, YouTube is a company with offices—especially its main campus in San Bruno—but the service itself runs on data centers and servers spread around the world.

Where YouTube “is” (online)

If you meant “where do I find YouTube on my device?”:

  • On a browser: go to youtube.com and sign in with a Google Account if you want subscriptions, history, and recommendations.
  • On mobile: open the YouTube app (usually preinstalled on Android; downloadable on iOS from the App Store).
  • On smart TVs and consoles: use the YouTube app from the device’s app store or built‑in apps; you typically sign in by scanning a QR code or entering a code shown on the TV.

A quick mental model

You can think of YouTube in three overlapping ways:

  1. A website – the page you open at youtube.com to watch and upload videos.
  1. An app – on phones, TVs, and game consoles, but connected to the same account and video library.
  1. A company and campus – a real set of office buildings in San Bruno and other cities where employees work on the platform.

In forum discussions, people asking “where is YouTube?” are often either confused about the physical HQ location or joking about recommendations suddenly hiding the videos they want—both senses show up in online threads.

TL;DR: YouTube “lives” on youtube.com and in its apps for users, and in the physical world its main home base is its headquarters at 901 Cherry Ave, San Bruno, California.
