A parking lot evaluation apparatus includes: an acquisition device configured to acquire information on an utterance made by a driver about a parking lot in a vehicle; and a deriving device configured to derive a parking difficulty level indicative of parking difficulty at the parking lot, based on the acquired utterance information about the parking lot. The acquisition device acquires, as an utterance about the parking lot, an utterance of the driver about the parking lot at the time when the vehicle is placed in the parking lot or around the parking lot.
