Kelly Simmons will leave the Football Association after 30 years of "seminal contribution" in developing the women's game in England, says FA chief executive Mark Bullingham.
Simmons will step down from her role as the director of the women's professional game in the summer before leaving the governing body next year.
She joined the FA in 1991.
"After over 30 brilliant years at the FA, Kelly has decided that it is time for a change," Bullingham said.
"Kelly has made a seminal contribution to the FA, and the growth and development of the women's game in particular, and will leave an enduring legacy."
