How many episodes of Naruto are there? I have been watching Naruto online, and there are no episodes available to watch after 301, even though I know there is a big war on that episode. Are there any more Naruto episodes? People have been saying there is an episode 700, but is that all manga?
There are 220 episodes in Naruto original anime series, which has been completed. Then Naruto Shippuden, which has 500 episodes in total. The series finished airing on the 23rd of March, 2017. 

You can stream and watch anime from anime-planet or some other anime streaming sites. Some of them may charge you, some of them may not. Best way to watch Shippuden is on Crunchy Roll.

There are 700 manga chapters and an extra 10 chapters in the Naruto: The Seventh Hokage and the Scarlet manga, which is set several years ahead of the final chapter (volume 72) of Naruto. 

With the conclusion of Naruto, we now have its spin-off/sequel, Boruto: Naruto Next Generations. This is currently airing on Crunchy Roll and is 18 canon episodes in as I am writing this. Also the manga is available to read for all the purists.
