Manager Roy Hodgson named his provisional 26-man squad on Monday morning, with that squad to be cut down to 23 before the tournament kicks off.
There were few surprises in the selection, as the England boss stuck by the players that helped the Three Lions qualify for France this summer.
There were some shocks though, as Manchester United striker Marcus Rashford was in alongside Manchester City midfielder Fabian Delph.
Wilshere and Townsend are two that are in though, and alongside Leicester City‘s Danny Drinkwater and Tottenham Hotspur duo Harry Kane and Dele Alli, Southampton's Ryan Bertrand and Liverpool's Nathaniel Clyne, they have shared their delight on Twitter.
Absolutely buzzing! I can't wait to meet up with the squad and start preparing for the euros. Thanks for all the messages. #England— Jack Wilshere (@JackWilshere) May 16, 2016
Huge honour to be named in provisional @England squad for the euros.... Will give my all over next few weeks to try and make final squad!— Andros Townsend (@andros_townsend) May 16, 2016
Attention now turns to the three players that Hodgson will cut from that group before the final squad is announced.
Rashford is likely to drop out, while it seems unlikely that Delph will be in after a disappointing year for him.
After that though it is hard to see who drops out, although much is likely to rest on whether Jack Wilshere and Jordan Henderson can prove their fitness.
