England will host a two-Test series against Canada in September before the new WXV tournament in New Zealand.
The Red Roses will kick off at 14:30 BST on Saturday, 23 September at Exeter's Sandy Park - England's men face Chile the same day in Lille in the Rugby World Cup (kick-off 17:45).
The venue for the second match is yet to be confirmed.
England won a fifth successive Six Nations title in April.
Their forwards coach Louis Deacon said: "We are delighted to be facing one of the world's best teams on home turf.
"Canada are a powerful team and present a fantastic challenge as we look to build on the success of our Six Nations campaign and continue improving as a squad.
"The two-Test series is the perfect preparation as we build up to the inaugural WXV tournament in New Zealand."
