Miguel José Yacamán (born August 17, 1946) is a Mexican physicist who has made contributions to the fields of materials science, nanotechnology, and physics.

His research has focused on the correlation of structure and properties in nanomaterials and he has developed electron microscopy methods to study nanoparticles and 2-D materials.

The present focuses of his work are to develop the nanoscale equivalent of high entropy alloys and new catalysts to produce cleaner fuels.

In June 2005, in collaboration with Jose Luis Elechiguerra (Fulbright Fellow), he published a groundbreaking paper on the inhibitory properties of silver nanoparticles against HIV-1.

According to the APS, Yacamán was chosen for the award “for [his] far-ranging, high-impact contributions to nanoscale science using electron microscopy, and for his mentorship and promotion of Latinos in physics, ranging from undergraduates to faculty.
