Ellis Fuller Lawrence (November 13, 1879 – February 27, 1946) was an American architect who worked primarily in the U.S. state of Oregon.
In 1914, he became the co-founder and first dean of the University of Oregon's School of Architecture and Allied Arts, a position he held until his death.
He received both his bachelor's and master's degrees at the Massachusetts Institute of Technology (MIT), the first school of architecture in the United States.
After graduation in 1902, Lawrence worked for the Boston architectural firms Peabody & Stearns and Andrews, Jaques & Rantoul as well as for architects John Calvin Stevens and Constant-Désiré Despradelle before he left to travel in Europe.
He lived in Portland the rest of his life and commuted to his work as dean and campus architect in Eugene.
