The MTV reality show - which focuses on the lives and loves of a group of hard partying guys and girls in Newcastle - will begin filming eight new 60 minute episodes this summer.
Kerry Taylor, Senior Vice President, Director of Television, Viacom International Media Networks (VIMN) UK & Ireland said: "It is fantastic to announce that 'Geordie Shore' is coming back for a fourth series! The response to the show since it launched in May 2011 has been truly phenomenal - both from a ratings perspective and across our social media platforms.
"The success of series one and two, combined with the demand and online buzz for series three, now just weeks away, has yet again demonstrated MTV's ability to create compelling content that continues to excite young 'millennial' audiences everywhere."
The cast recently filmed the third series of the show in Cancun, Mexico where Ricci Guarnaccio proposed to co-star Vicky Pattison.
Ricci, 25, said: "When I came into the 'Geordie Shore' house I had been single for a long time and certainly didn't expect to fall in love - but that's what happened. I couldn't be happier with Vicky and know I want to spend the rest of my life with her."
Vicky, 24 - who dumped her boyfriend Dan Matthews for Ricci - added: "I'm so excited to be engaged to Ricci. He's an amazing person and I knew that as soon as he walked through the door and into the house, there was an instant connection between us. I'm very lucky to have found him."
'Geordie Shore: Chaos in Cancun' starts on Tuesday June 26 at 10pm on MTV.
