Bieten, Laubbieten, Lab bietn or Labbieten (in South Tyrol) or Bavarian Poker () is a card game that is popular in the Austrian Tyrol and the Bavarian Prealps. It used to be a game frequently played by timber rafters and muleteers. It can be seen as a precursor to the traditional Tyrolean game of Perlaggen. The unusual feature of Bieten is the nature of the competition. The players have the option, even if they have a poor hand, of persuading their opponent(s) to cave in through skilful bidding (Bieten) and bluffing.
