The competition was launched in 1962 and has seen the likes of Liverpool, Celtic, Borussia Dortmund and Benfica take part, with Stoke City the cup's current holders.
This summer's tournament will see Wolves joined by Swiss champions BSC Young Boys, 13 time Uhrencup winners FC Basel and Feyenoord, who finished fourth in this season's Eredivisie.
Wolves will take on FC Basel and BSC Young Boys between 10th-14th July. Specific date, venue and ticket information released in the coming weeks on wolves.co.uk.
