Mónica Alicia Clapp Jiménez Labora is a mathematician at the Universidad Nacional Autónoma de México (UNAM) known for her work in nonlinear partial differential equations and algebraic topology.

Clapp was born in Mexico City.^[1] She graduated from UNAM in 1974. Clapp then graduated with her Ph.D from Heidelberg University in 1979, and has been a faculty member at UNAM since that time.^[2]

Clapp has been an editor of the journals Boletín de la Sociedad Matemática Mexicana and Aportaciones Matemáticas.^[1]

In 2012, Clapp became a fellow of the American Mathematical Society.^[3] She is also a member of the Mexican Academy of Sciences.^[4]
