The Magpies first deal was completed this week when Matt Targett made a permanent switch to Tyneside after the on-loan Aston Villa defender played a key role in helping secure Premier League safety with a remarkable run of form during the second half of the Premier League season.
Thoughts are quickly turning towards their next month as new sporting director Dan Ashworth looked to replicate the success of the January transfer window.
The additions of Kieran Trippier, Chris Wood, Bruno Guimaraes, Dan Burn and Targett laid the platform for a march up the Premier League table and Magpies boss Eddie Howe will hope to add further quality to his squad over the close-season.
Some intriguing names from the Premier League and around Europe have already been suggested as possible targets for what could be an eventful summer on Tyneside.
Reims star Hugo Ekitike and Lille defender Sven Botman are two players Newcastle hope to sign over the coming weeks.
Newcastle World takes a look at the players linked with a move to St James Park as media speculation increases with the opening of the window now just weeks away.
