The invention discloses a method and device for evaluating the geometric irregularity state of a railway turnout zone track, and the method comprises the steps: calculating the turnout positioning index of the railway track according to the geometric detection data of the railway track; dividing the track geometric detection data into different turnout sections according to the turnout machine account point and rail point mileage information; the turnout section comprises a plurality of groups of turnouts; determining a to-be-evaluated mileage section of each turnout in the turnout section according to the track geometric detection data, the turnout positioning index and the turnout machine account switch rail tip mileage information of each turnout section; according to the track geometric detection data of each turnout, calculating a turnout zone track quality index of the mileage section to be evaluated of the turnout; the turnout zone track quality index is used for representing the sum of a plurality of
