To do this programmatically, use IClass.AddField. (Do NOT use IFieldsEdit.AddField on an existing dataset).

Thanks. I had been trying to do it through ArcCatalog, but this did what I needed. – Britt Wescott Aug 30 '10 at 15:48
Is there any way to modify an existing field name (not an alias)? – Britt Wescott Aug 30 '10 at 19:25

Modifying existing field names is at top of ArcGIS Desktop Ideas that users would like to see Esri implement: http://ideas.arcgis.com/ideaList?c=09a300000004xET&category=ArcGIS+Desktop&sort=top – PolyGeo Sep 08 '10 at 00:01

In Python, using the ArcPy site package, you'd use

arcpy.AddField_management(.....)

You cannot modify the actual field name of an existing field. I would LOVE to be able to do that, but even if they implement it, I bet it'll be similar to renaming in SQL. That is, the net effect is a renamed field, but the underlying operation is: make new field with new field name, copy contents from old field, drop old field name.
