Helene Kröller-Müller, German-Dutch art collector and philanthropist, founded the Kröller-Müller Museum (died 1939)

Helene Emma Laura Juliane Kröller-Müller was a German art collector. She was one of the first European women to put together a major art collection. She is credited with being one of the first collectors to recognise the genius of Vincent van Gogh. Her entire collection was eventually sold to the Dutch government, along with her and her husband, Anton Kröller's, large forested country estate. Today it is the Kröller-Müller Museum and sculpture garden and Hoge Veluwe National Park, one of the largest national parks in the Netherlands.

The Kröller-Müller Museum is a national art museum and sculpture garden, located in the Hoge Veluwe National Park in Otterlo in the Netherlands. The museum, founded by art collector Helene Kröller-Müller within the extensive grounds of her and her husband's former estate, opened in 1938. It has the second-largest collection of paintings by Vincent van Gogh, after the Van Gogh Museum. The museum had 380,000 visitors in 2015.
