The actor/writer, who starred in the 2002 movie adaptation of Wilde's The Importance of Being Earnest, will be the guest of honour at the Pere Lachaise Cemetery ceremony.
Wilde's grandson, Merlin Holland, personally invited Everett to attend.
The new tombstone will be cased in protective glass in a bid to prevent Wilde devotees from actually touching the grave marker. It has become customary for fans to leave a kiss mark on the stone.
Everett is currently completing a script detailing the latter years of Wilde's life.
The literary legend died from meningitis in 1900.
