Abstract: We report the discovery of an H-alpha bow-shock nebulae associated with the energetic pulsar B0740-28. This is only the second southern pulsar to be associated with H-alpha bow-shock emission, and the fourth overall. The nebulae extends over some 45'' and shows a distinctive key-hole shape and appears to be closed at the rear. The H-alpha flux over the entire nebula is around two orders of magnitude fainter than the J0437-4715 and B1957+20 nebulae and indicates that the pulsar is likely located in the warm ionized phase of the interstellar medium.
