This paper argues that Övdalian has the vocative case. Although the system of the four standard cases is not as strong as it used to be, there is a set of vocative forms that are still commonly used today, although they are restricted to a few categories of words. The system is not the one inherited from Proto-Indo-European, but must be a later innovation. However, there are interesting similarities between Övdalian and other languages, suggesting universal tendencies for the vocative category.
