A lane line recognition apparatus includes an imaging device, a lane-line-search-region setting section, a light-streak-search-region setting section, a light-streak determination section, a light-streak-reaching determination section, and a mask processing section. The imaging device is to be mounted on a vehicle and captures an image of a traveling environment in front of the vehicle. The lane-line-search-region setting section sets a lane-line search region on the image. The light-streak-search-region setting section sets a light-streak search region adjacently to the lane-line search region. The light-streak determination section determines whether a light streak that crosses, in a vertical direction of the image, the light-streak search region is found. The light-streak-reaching determination section determines, if the light streak is found, whether the light streak reaches the lane-line search region. The mask processing section performs, if the light streak reaches the lane-line search region, a mask process on the light streak.
