The Crooked Forest (Polish: Krzywy Las) is a grove of oddly-shaped Scots pine trees located in the village of Nowe Czarnowo near the town of Gryfino, West Pomerania, in north-western Poland.

Each pine tree bends sharply to the north, just above ground level, then curves back upright after a sideways excursion of one to three meters (3–9 feet).

[2] It is generally believed that some form of human tool or technique was used to make the trees grow or bend this way, but the method has never been determined, and remains a mystery to this day.

It has been speculated that the trees may have been deformed to create naturally curved timber for use in furniture or boat building.

[4][5][6][failed verification] The forest was featured in season 1, episode 4 of The UnXplained on the History channel titled "Unnatural Nature" that first aired on 9 August 2019.
