....goalkeeper Tyrell Belford from Sky Bet League One side Swindon Town and striker John Cofie on a free transfer.
Belford joins the club with player-manager Andy Bishop planning to make the 22-year-old his number one goalkeeper.
No recall clause has been arranged meaning Southport will keep Belford on loan for the duration of the oncoming season.
Belford has represented England at under-17 level and impressed after being given first-team opportunities at Swindon during the middle of last season.
Injury hampered the end of Belford's season but the youngster has been declared fit to continue his development at Southport.
Tyrell is the son of former Rugby Town, Atherstone Town and Tamworth manager Dale Belford and brother of Stranraer goalkeeper Cameron Belford.
Bishop said: "I'm delighted to have signed Ty Belford and I've been working on the deal for some time. I've followed his career since he was at Liverpool and watched his progress at Swindon. Ty has made appearances in League One and fought for the number one spot. I've been working hard in this area to find the right man and believe Ty is that person.
"He's on a season-long loan but I see him as our player because there's no recall clause. I'd like to thank Swindon for all their help getting the deal done."
Cofie (pictured) most recently made twenty-two appearances for AFC Telford United last season.
He started his career at Burnley and commanded a £1m transfer at just 14 years old to Manchester United - where he gained first-team experience at Royal Antwerp, Sheffield United and Notts County on loan.
Born in Aboso, Ghana, Cofie moved to England at a young age and has been capped by England at under-17 level.
