Provided is an external environment recognition device capable of determining a place where a host vehicle can safely evacuate at the time of recognition of a specific vehicle by using a plurality of cameras in combination even in a vehicle not equipped with a distance sensor such as a radar, a LiDAR, an ultrasonic sensor, or an infrared sensor. Therefore, an external environment recognition device includes: a plurality of cameras installed so as to have a plurality of stereo vision regions in which at least a part of a visual field region overlaps around a host vehicle; a three-dimensional information generation unit that generates three-dimensional information by performing stereo matching processing in each of the plurality of stereo vision regions; a three-dimensional information accumulation unit that accumulates the three-dimensional information generated during traveling of the host vehicle in time series; and a three-dimensional information update unit that updates the three-dimensional information accumulated in the three-dimensional information accumulation unit using three-dimensional information newly generated by the three-dimensional information generation unit.
