Ахерна́р (α Eri / α Эридана / Альфа Эридана) — ярчайшая звезда в созвездии Эридана и девятая по яркости на всём ночном небе. Расположена в южной оконечности созвездия. Из десяти ярчайших звёзд Ахернар самая горячая и самая голубая. Звезда необычайно быстро вращается вокруг оси, из-за чего имеет сильно приплюснутую форму. Ахернар является двойной звездой.
