Ted Bohdan Belytschko (January 13, 1943 – September 15, 2014) was an American mechanical engineer.{{cite book|url=https://books.google.com/books?id=NVFAAQAAIAAJ&q=%22Belytschko,+Ted%22+AND+%221943%22|title=Supplement to Who's who in America|date=27 April 1987|publisher=Marquis Who's Who|isbn=9780837971001|via=Google Books}} He was Walter P. Murphy Professor and McCormick Professor of Computational Mechanics at Northwestern University.{{cite web|title=Ted Belytschko |url=http://www.mech.northwestern.edu/web/people/faculty/belytschko/|work=Department of Mechanical Engineering|publisher=Northwestern University |accessdate=June 2, 2011}} He worked in the field of computational solid mechanics and was known for development of methods like element-free Galerkin method and the Extended finite element method.

Belytschko received his B.S. in Engineering Sciences (1965) and his Ph.D. in Mechanics (1968) from the Illinois Institute of Technology. He was named in ISI Database as the fourth most cited engineering researcher in January 2004. He was also the editor of the International Journal for Numerical Methods in Engineering. He died at the age of 71 on September 15, 2014.{{cite web|title=Ted Belytschko|url=http://www.mccormick.northwestern.edu/news/articles/2014/09/ted-belytschko-renowned-researcher-scholar-and-mentor-passes-away.html|work=Department of Mechanical Engineering|publisher=Northwestern University|accessdate=September 15, 2014}}
