Out of those called up, only three have been first time regulars this season for the Hammers, who despite defeat at home to Crystal Palace on Saturday have enjoyed a reasonably good start to the season, sitting in eighth in the Premier League.
With the international break upon us, here is a look at which players are representing their countries this month and when and where you can catch them in action.
All TV/live stream information relates to UK availability.
Declan Rice (England)
Rice has been an ever present in the midfield for West Ham this season, breaking up play and putting the Hammers back on the front foot throughout games this term.
Ever since Rice declared he would play for England over the Republic of Ireland in February, Three Lions manager Gareth Southgate has included Rice in his last four squads and is clearly a big fan of the 20-year-old. He started the midfielder in both of England’s victories last month against Bulgaria and Kosovo.
Rice is the only player in the West Ham squad who has been called up for the England squad and is set to start against Czech Republic on Friday in their UEFA European Championship qualifier in Group A.

Andriy Yarmolenko (Ukraine)
The winger has been in excellent form so far this term, scoring three times in the Premier League already, one more than he managed in the whole of last season.
He joins up with a Ukraine side who currently sit top of Group B in Euro 2020 qualifying, with 13 points from five games. They sit five points clear of second placed Portugal, albeit the Portuguese do have a game in hand.
Yarmolenko will look to keep up his good form and help Ukraine maintain their lead at the top of the group when they face Lithuania and then Portugal, with both being at home.
