Ulster
I think in the context of sport and the British and Irish Lions there is no distinction.
Politically I understand your point that Northern Island is part of the UK though I think Ulster province is bigger than just N.I.
It use to be just the British Lions and some from NI did play on the British Lions team. However it was changed years later to include those from the ROI and it became the British and Irish Lions.
