We report on the discovery and follow-up observations of a 63-ms radio pulsar, PSR J1105-6107. We show that the pulsar is young, having a characteristic age of only 63 kyr. We consider its possible association with the nearby supernova remnant G290.1-0.8 (MSH 11-61A) but uncertainties in the distances and ages of both objects preclude a firm conclusion. Proof of an association would be provided if the pulsar's velocity is measured to be ~ 650 km s (-1) directed away from the remnant center, for a distance of 7 kpc and assuming the pulsar's characteristic age is the true age. The pulsar's spin-down luminosity, 2.5 x 10(36) erg s(-1) , is in the top 1% of all known pulsar spin-down luminosities. Given its estimated distance, the pulsar is likely to be observable at high energies. Indeed, it is coincident with the known CGRO/EGRET source 2EG J1103-6106; we consider the possible association and conclude that it is likely.
