Inside is a 2011 American social horror thriller film brought to viewers through a partnership between Intel and Toshiba.

Directed and written by D. J. Caruso and starring Emmy Rossum, the experience is broken up into several segments across multiple social media platforms, including Facebook, YouTube, and Twitter. Viewers are challenged to help Rossum's character, Christina, to safely escape her predicament. The film bears some similarities to the non-social 2008 film Untraceable in that it involves kidnapping and an Internet audience as part of the plot.

The first in a series of episodes was released on the website on July 25, 2011 for those participating in the "real-time experience". The whole film became available for online viewing on September 6, 2011 on their website, though both the website and YouTube channel no longer exist.
