A lane departure warning apparatus that issues a warning for a lane departure of a vehicle monitors a change amount of a location of the vehicle relative to a division line that defines a travelling lane, in a case where the lane departure warning apparatus has detected the lane departure of the vehicle from the travelling lane. The lane departure warning apparatus is issues the warning to an output device in at least one of cases in which (i) the change amount monitoring part determines that the change amount of the location of the vehicle is equal to or greater than a first threshold value and (ii) the change amount monitoring part determines that the change amount per a unit of time is equal to or greater than a second threshold value.
