BBC Two will broadcast a 25th anniversary special before the end of the year - a one hour show marking 25 years since his debut on BBC Radio back in 1992.
A BBC One series will then air next year.
Both are to be produced by Baby Cow Productions.
Shane Allen said: "Alan Partridge is in the top tier of comedy characters of all time, it fills my comedy heart with joy to welcome him back to BBC One and BBC Two."
