Southampton will host Ajax, Udinese, Arsenal and Rangers as they prepare for their return to the Premier League after a seven-year absence.
Dutch champions Ajax will visit St Mary's on July 28th whilst Serie A side Udinese will visit on August 11th - just a week before the season gets underway.
These games will be preceded by the Markus Liebherr Memorial Cup on July 14th, when the Saints will host a round robin tournament with Arsenal and Rangers.
The newly promoted side will also host Wolves on August 4th and will travel to Bristol City three days later.
Nigel Adkins is also planning a seven-day training camp in Evian-les-Bains, where they are expected to play two games, one being against Ligue 1 side Evian.
