The 100 is one of the most popular tv shows of the last few years, and we can see why – it’s pretty awesome. If you want to watch it online (up to and including season 5) then here are a few options (we checked these as recently as March 2019):


You see the yellow button? That is how you start the free trial, it is 100% free and you can click the image above to be taken to this page.

Just cancel before the 30 days is up and you don’t pay anything, simple. If you’re wanting to watch The 100 for free and in amazing quality right now, then a free trial with Amazon Prime Video is your best option. 

  • Update – we had to remove 2 other sites we had recommended as The 100 was taken off them.

So there you have it, a few options for watching the 100 online free, seasons 1-5. Happy streaming!
