Dill is an annual herb in the celery family Apiaceae. It is native to North Africa, Iran, and the Arabian Peninsula; it is grown widely in Eurasia, where its leaves and seeds are used as a herb or spice for flavouring food.

Dill has been found in the tomb of Egyptian Pharaoh Amenhotep II, dating to around 1400 BC. It was also later found in the Greek city of Samos, around the 7th century BC, and mentioned in the writings of Theophrastus (371–287 BC). In Greek mythology, the dill was originally a young man named Anethus who was transformed into the plant.
