The former Eagles striker has returned to Selhurst Park to serve as a club ambassador.
Johnson is still held in very high regard amongst Palace supporters after spending four successful years at Selhurst Park following his arrival from Birmingham City in 2002.
In his time with the Eagles, the striker scored 85 goals in 161 appearances, including hitting 32 in all competitions as the club won promotion to the Premier League in 2004 and winning the golden boot with 21 goals in 37 appearances in his only top-flight season at the club.
That form also earned him a place in Sven Goran-Eriksson's England squad and a subsequent recall under the Swede's successor Steve McClaren.
He left to join Everton for around £8.5 million in 2006 but never managed to recapture the lethal form of his Palace days at Goodison Park, or at later clubs Fulham or Queens Park Rangers.
Johnson returned to Selhurst Park as a player-coach for a brief spell last season, but he has now rejoined the club in a more fixed role which will involve both coaching and ambassadorial duties.
The 35-year told the club's official website that he was delighted to be back at the club where he enjoyed so much success.
He said: "It’s my third spell here so I’m delighted to be back and massive thanks to the Chairman and [CEO] Phil Alexander for keeping me in their minds and asking me back to be part of the club.
"The role will see me involved in a number of different ways, it involves mentoring with some of the academy players, working in the community, matchdays, corporate events, team events, there’s quite a lot to be getting involved with and cannot wait to get started."
Unsurprisingly, the return of one of the most popular Palace players in recent years was heralded by Eagles fans on Twitter.

If you are too young to have watched him in his prime, you missed something special.
