The 19-year-old was one of five British players, including Jack Wilshere, to agree fresh terms at the Emirates Stadium on Wednesday.
Oxlade-Chamberlain tweeted: "Delighted to have signed a new contract along with the rest of the young lads. Really looking forward to the coming years at this club!"
The England international joined the Gunners from Southampton in summer 2011 for around £12m.
