Where can I watch old Nickelodeon cartoons in the USA?

In the USA, old Nickelodeon cartoons can often be found in a few places, but availability changes a lot by title and over time:

• Paramount+ — a good place to check for many Nickelodeon titles.
• Pluto TV — sometimes has free, ad-supported Nickelodeon programming or channels.
• Digital stores like Amazon Prime Video, Apple TV, or YouTube — some seasons or episodes may be available to buy or rent.
• DVD/Blu-ray — useful for older series that are hard to stream.
• Other streaming services — some Nickelodeon shows may also appear on services like Netflix, depending on the title and current licensing.

Because streaming rights change often, the exact shows on each service can differ. If you’re looking for a specific cartoon, search that title directly on Paramount+, Pluto TV, and the major digital stores, and check the current official listings.
