Chuhuiv Observational Station (or Chuguev Observational Station) of the Institute of Astronomy of Kharkiv National University is an astronomical observatory founded in the early 1960s near the village of Ivanovka, Chuhuiv Raion, Kharkiv Oblast, Ukraine. In 2022 the observational station was occupied and severely plundered by Russian soldiers, who during 6 months of occupation stole or damaged most of the scientific equipment.{{cite web|url=https://universemagazine.com/yaki-perspektyvy-chuguyivskoyi-observatoriyi-pislya-okupacziyi/|title=Перспективи Чугуївської обсерваторії після окупації|author=|date=29 May 2023|website=The Universe.
