Yes. There are a number of binary stars scattered about the sky, and there is always one visible at night (unless it is cloudy!)

In the northern hemisphere, one of the most famous "visual binary" stars - two stars that appear to be next to each other, but which are not gravitationally bound - are the middle "star" in the handle of the Big Dipper. They are Mizar and Alcor. In Roman times, the Legions used these as an eye test; if you could see two stars, then your vision was good enough to be an archer. If you only saw one, then it was not.

The star Mizar itself is a true "double star"; two stars orbiting their common center of gravity.

Anywhere north of 30 degrees north latitude, these stars (and the Big Dipper itself) are circumpolar; they never set.
