Keith Roberts Porter (June 11, 1912 – May 2, 1997) was a Canadian-American cell biologist. He created pioneering biology techniques and research using electron microscopy of cells. Porter also contributed to the development of other experimental methods for cell culture and nuclear transplantation. He was also responsible for naming the endoplasmic reticulum, conducting work on the 9 + 2 microtubule structure in the axoneme of cilia, and coining the term "microtrabecular lattice." In collaborations with other scientists, he contributed to the understanding of cellular structures and concepts such as compartmentalization, flagella, centrioles, fibrin, collagen, T-tubules and sarcoplasmic reticulum. He also introduced microtome cutting.
