Rotate ArcMap Data Frame
From time to time, you might find a need to rotate your data frame. Many people do not realize that it is even possible. They find that their map would look better if they could just make the slight tweak. Well this task can be done with just a few clicks.
1. Open the data frame properties. Notice the orientation of the United States.
2. Under the general tab, enter the desired rotation angle for the data frame.
With this new rotation angle set, your data frame will reflect the change.
Also note that on the layout view, the north arrow will rotate with the data frame.
If you rotate your data frame often and would like a more interactive way to do it, then turn on the Data Frame Tools toolbar from the tools menu.
With this tool bar you can click the rotate button and rotate the data frame interactively. There is also a reset button as well to bring the data frame back to true north.
