A tidally locked planet is one that turns to always face its parent star, but what's the term for a planet that doesn't turn at all? (i.e. with a day/night cycle that's equal to exactly one year)

There are no examples of this as far as I’m aware, every object in space rotates. 

You could examine the orbit of Uranus, which rotates on its side, producing a relatively similar effect. The poles get sunlight for half a year, and then no sunlight for the other half.
