Hands down, Ron Swanson from Parks & Recreation.
He's a libertarian who firmly believes in his right to self-determination, but doesn't force that view on those around him; he lets them live their own lives and is there to help them whenever they may need. I do somewhat envy his ability to ignore the meaningless bullshit around modern life, how he paddles his own canoe and strives not to be in anyone's way.
But most importantly, he's fond of pretty, dark haired women, and breakfast food, and who can argue with that?
