A complete theory for dipolar antiferromagnetic surface spin waves is given. Analytic forms are derived for the dispersion relation and regions of stability. Applications to representative uniaxial antiferromagnets (Mn${\mathrm{F}}_2$, GdAl${\mathrm{O}}_3$,${\mathrm{F}}_2$) are shown and possible experimental methods for verification are discussed. The case of exchange-dominated antiferromagnetic surface spin waves is briefly mentioned.
