A “Core Four” Yankee no longer feels welcome in The Bronx.

Jorge Posada told The Post’s Joel Sherman and Jon Heyman in the latest episode of “The Show” podcast that he believes the Yankees no longer want him around after being asked about potentially helping the team.

“It’s gotta be the right — I mean, I could, but I don’t think they want me there to tell you the truth,” Posada said on the episode, which premiered Tuesday afternoon.

“I don’t feel welcome when I go there, you know? Even in spring training, I don’t feel like — I’m just like, I don’t know, like, I don’t feel welcome. I don’t feel like they want me there, so I don’t go.”

Posada’s shocking reveal came after being asked by Sherman about whether the Yankees need someone besides manager Aaron Boone who cares about the team’s brand and has the fire that the former catcher exhibited during his career to stand up and say that certain plays are “unacceptable.”

The 56-year-old won over fans during his 17 years in The Bronx from 1995-2011 with his fiery passion and offensive skills, winning five titles as part of the Core Four alongside Hall of Famers in shortstop Derek Jeter and closer Mariano Rivera plus lefty starter Andy Pettitte.

When pressed about what would make him feel that way, he didn’t offer a specific moment but referenced the tough end to his Yankees career.

“I don’t know what happened. I’d rather just move forward,” Posada said. “My last season of my career was a really tough one when it comes to handling everything in my part and also the Yankees toward Jorge Posada. So, it’s tough to go back and feel that again.”

Posada’s final season in 2011 featured public disagreements with the team about his playing time and being shifted to designated hitter.

He believed the front office made the call, not then-manager Joe Girardi, and clarified Tuesday that he talked to Girardi about the decisions but not general manager Brian Cashman or owner Hal Steinbrenner.

“That I never got a chance to fight for my job was the toughest part,” Posada said at the time. “I don’t have an issue or a problem with Joe.”

Cashman, who declined to comment for this story, acknowledged the rocky ending at the time.

“Sometimes there are rough patches, but you try to get through them,” Cashman said then. “We obviously had a rough patch this year … but we all fought through it.”

Posada indicated to Sherman and Heyman that he doesn’t have regrets about going public with his thoughts.

Posada appeared behind the plate just one time in 2022 compared to 90 starts as the designated hitter and 14 as the first baseman, and posted a .714 OPS.

The Yankees instead went with Russell Martin as their starting catcher during a season that ended with an ALDS loss to the Tigers.

Posada has been around the franchise despite feeling unwelcome, having attended several Old Timers’ Day and appearing for the 1998 championships team’s 25th anniversary in 2023.

“I’m gonna express the way I feel and … if something’s wrong, I’m gonna tell you,” Posada said. “That’s the way I played the game. We wanted to win and we wanted to be there to do the right things. I’m very honest and that’s my probably my toughest thing with people. I’ll tell you straight up what’s wrong.”

Since he hung up the cleats, Posada has stayed involved in baseball.

He worked under Derek Jeter in the Marlins’ front office and also served as the bench coach for Team Italy during this year’s World Baseball Classic.

He said he enjoyed his Marlins role, especially since he didn’t have to be there all the time.

Posada is now finding joy in being around his family.

As he watched the 2026 postseason from afar, Posada noted that he expected a better performance from the Yankees.

“They keep coming up short and it’s just about getting hot, being healthy and all at the right time,” Posada said. “I felt like the pitching was phenomenal. I feel like they had everything going forward. Losing (Aaron) Judge, not putting any excuses, but losing judge is a big piece in the middle of the lineup. And then you get guys that  they got in the trade and I felt like they got more of the same. So it was tough to see ‘it come up short because I thought they were gonna go a little further.”
