The Max Planck International Research Network on Aging (MaxNetAging) is a virtual institute for the advancement of research on the causes, patterns, processes, and consequences of aging. It is part of the broad activities carried out by the Max Planck Society in this field.

Under the auspices of the Max Planck Society, MaxNetAging provides a platform for an international collaboration endeavor between 21 Max Planck Institutes, 1 Emmy Noether research group and outstanding scholars from other institutions. The network's interdisciplinary focus includes political science, law, sociology, anthropology, economics, history, art history, history of science, demography, mathematics, biology, medicine, cognitive and brain sciences, psychology, and human development.

MaxNetAging consists of a doctoral and postdoctoral funding program (MaxNetAging Research School), fellowships, research workshops, and annual conferences.

MaxNetAging was founded in 2004 by Paul B. Baltes (1939-2006), Max Planck Institute for Human Development in Berlin.

Since 2007 James W. Vaupel, Director at the Max Planck Institute for Demographic Research, has been the Director of MaxNetAging.
