I know both parties to a relationship and now know that one person is cheating. What, if anything, should i say to the non cheating person?

That would be a judgement call requiring me to know a great deal more than the scant details you mention. If it was me, the default answer would be say nothing...anything else may be seen as taking sides, which would be a no-win situation for you in the long run.

nothing.
but a word, perhaps, to the cheater.

That would be the best place to start, if only to let the cheater know s/he's putting you in an awkward position...after all, you may want to able to look the party being cheated on in the eye someday...

It's a toughie - saying nothing will look to the innocent party like you've taken the side of the cheater.

I would go to the cheater first and insist that s/he confess/end the affair/end the relationship with the 'cheatee' - if not, you will. Admittedly this may damage your relationship with the cheater, but then what sort of friend allows you to end up in that situation? And do you really want a liar and a cheat as one of your friends in the first place?

I know it sounds harsh, but I come down on the moral side with things like this. The innocent party deserves your loyalty more than the cheater.

I see NOTHING tough about this one. If I had all the details I believe it would be as much my business as it is yours now. NONE!
