We introduce and study the space of almost periodic ultradistributions of Beurling type and characterize it in terms of classical Bohr almost periodicity. To this aim we establish a structure theorem for the bounded ultradistributions. Application is made to the Dirichlet Problem for the half plane with almost periodic untradistributional boundary values.
