Liga Purmale (born 4 October 1948 in Dundaga, Latvian SSR) is a Latvian painter.
At a young age she moved to Riga from the Latvian countryside to study painting, first at the Janis Rozentals Art High School and then at the Latvian Academy of Art.
In the 1970s she and Miervaldis Polis, who was her husband at the time, started a new trend of photorealism in Latvian painting.
