In your HTML file make sure you declare your underscore js file before your backbone js file.

I'm guessing that you're using an old version of Backbone, something pre-0.5.0. Backbone.Router used to be called Backbone.Controller but it was renamed as part of 0.5.0:

0.5.0 — July 1, 2011

[...] Controller was renamed to Router, for clarity.

The second Google hit for "backbone tutorial" points me at this tutorial which uses 0.3.3. There seems to be a lot of people using 0.3.3 asking questions about Backbone lately so the Google results are probably the problem.

You should upgrade to the latest version (0.9.2) of Backbone, you can get it from the Backbone website. You should probably be using the latest version of Underscore (1.4.2) as well, you can get that at the Underscore website.

For some reason your Backbone object does not have the Router property on it. Are you overwriting it somewhere?
