Eastern New Mexico University (abbreviated ENMU), frequently called Eastern is a state university in Portales, Roosevelt County, New Mexico, United States. It is the most recently founded state university in New Mexico (legislated in 1927, opened in 1934).

ENMU’s athletic teams participate in the NCAA Division II Lone Star Conference. The Men’s teams are nicknamed the Greyhounds, and the Women’s teams are nicknamed the Zias. In early 2015, students and faculty voted to discontinue the Zia nickname and become the Lady Greyhounds; the female counterpart to the men’s Greyhounds.
