The **Geometry Festival** is an annual [mathematics](/source/Mathematics) conference held in the [United States](/source/United_States).

The festival has been held since 1985 at the [University of Pennsylvania](/source/University_of_Pennsylvania), the [University of Maryland](/source/University_of_Maryland,_Baltimore), the [University of North Carolina](/source/University_of_North_Carolina), the [State University of New York](/source/State_University_of_New_York) at Stony Brook, [Duke University](/source/Duke_University) and New York University's [Courant Institute of Mathematical Sciences](/source/Courant_Institute_of_Mathematical_Sciences). It is a three day conference that focuses on the major recent results in geometry and related fields.[1]
