Henosepilachna vigintioctopunctata is a species of beetle in the family Coccinellidae. It is commonly known as the 28-spotted potato ladybird or the Hadda beetle. It feeds on the foliage of potatoes and other solanaceous crops. It was previously called Epilachna vigintioctopunctata and is a cryptic species complex. It is very often confused with a closely related species, Henosepilachna vigintioctomaculata, which occurs in Russia, China, Japan, and Korea, and is given the same "common name".

This species is native to southeastern Asia, primarily India, but has been accidentally introduced to other parts of the world, including Australia and New Zealand. It has also been recorded from Brazil and Argentina, beginning in 1996.

This species causes damage to agricultural crops primarily in the family Solanaceae, especially potatoes; other crops include pumpkin, turnips, radishes, beans and spinach.
