Margaret Graver is Aaron Lawrence Professor of Classical Studies at Dartmouth College. Educated at the University of North Carolina and at Brown University, she has been a member of Dartmouth's faculty since 1996. 

She is a specialist in Hellenistic and Roman philosophy, with an emphasis on Stoic moral psychology. Her most-cited work is Stoicism and Emotion (Chicago, 2007), which treats all aspects of emotional response and emotive traits of character in early Stoicism. She has also written extensively on Seneca's philosophical letters and treatises, especially in Seneca, The Literary Philosopher (Cambridge, 2023). As a translator, she has published a translation of Cicero's Tusculan Disputations with introduction and philosophical commentary (Cicero on the Emotions, Chicago, 2002) and, collaborating with A.A. Long, a complete annotated translation of Seneca's Letters on Ethics (Chicago, 2015), as well as a smaller collection titled Fifty Letters of a Roman Stoic (Chicago, 2021). With Sean McConnell and Nathan Gilbert, she co-edited Power and Persuasion in Cicero's Philosophy (Cambridge, 2023). Special areas of interest in her articles and chapters include Stoic compatibilism, friendship and the doing of favors, honor, and therapeutic strategies in philosophical writing. Her current major project is a monograph on Cicero's lifelong engagement with Stoic ethics.
