DeMya Chakheia Walker (born November 28, 1977) is a professional basketball player from the United States.

However, prior to the start of the 1999 WNBA season, Walker was assigned to the Minnesota Lynx for its pre-season training camp, but was cut from the team final roster shortly afterwards.

In 2000, she signed a free agent contract with the Portland Fire, and played with them for three seasons until the team was disbanded due to financial difficulties.

Walker played the 2003–08 seasons with the Monarchs, and even helped the team win the 2005 WNBA Finals by defeating the Connecticut Sun, three games to one.

When the Monarchs folded prior to the 2010 WNBA season, Walker was selected by the Connecticut Sun in a dispersal draft.
