The 47-year-old former England men’s seamer will replace Lisa Keightley, who left the position in August.
“It’s very exciting to have been appointed Head Coach of the England Women’s team. It’s a new challenge and one that I can’t wait to get stuck into,” Lewis said.
“I’ve watched from a distance over the last few years and it’s clear that there are a lot of reasons to be optimistic about this team’s chances going forward.”
Lewis and his new team will depart for West Indies on Nov. 29.
