Not unless your opponent also has other pieces on the board.

No other pieces on the board. Just his king and knight, and my king.

It's a draw in every situation then.

A single piece can only produce mate when it can cover at least two squares, the square the king is on, (obviously!) as well as the square the king was on the move before. With a knight, that means a pair of touching diagonal squares. Only a situation where those diagonals are the complemented by those denied to the mated king by the other king AND something else. Even when you somehow manage to get the king into a corner, the two diagonals will not be able to include the corner piece itself.

I understand it takes 3 Knights to force mate. I've never set it up and tried, though. I'm sure one of the basic endings web pages can demonstrate it.
