Heracleum persicum, commonly known as Persian hogweed or by its native name Golpar (Persian: گلپر) is a species of hogweed, a perennial herbaceous plant in the carrot family Apiaceae. It grows wild in humid mountainous regions in Iran and some adjacent areas. Having been introduced in the 1830s, it has spread across Scandinavia. It is now very common in northern Norway, where one of its names is Tromsø palm. The plant has also been spotted in Sweden. In Finland, it has been declared an invasive species.

Persian hogweed is a polycarpic perennial, that is, a mature plant flowers and bears fruit season after season.
