A turning control device includes: a target steering angle calculation unit configured to calculate a target steering angle of a turning mechanism, based on a second steering angle of a steering mechanism; a steering angular displacement calculation unit configured to, when a third steering angle, the third steering angle being either a first steering angle of the turning mechanism or the second steering angle, is in a range from a maximum steering angle that the third steering angle can take to a first threshold steering angle, calculate a steering angular displacement of the third steering angle with the first threshold steering angle used as a reference; a steering angle correction value calculation unit configured to calculate a steering angle correction value according to at least the steering angular displacement; and a corrected target steering angle calculation unit configured to correct the target steering angle with the steering angle correction value.
