Amar’e Stoudemire never won an NBA championship, but now has eyes on winning the Israeli League and European title.

The former Knicks All-Star officially announced Monday he was joining Hapoel Jerusalem on a two-year contract after retiring from the NBA last week. Stoudemire, 33, said he turned down several offers from non-playoff-caliber NBA teams to fulfill “a dream come true.”

Stoudemire will have to sell his ownership stake in the team in order to join the roster. He will be penciled in at center.

“This is a very, very emotional decision for me because at this moment, I have to uproot my family who have been stable in the U.S. to move to a different country,’’ Stoudemire said at a Garden press conference. “It’s also a spiritual journey as well. The next phase of my career – people have documented my journey with the Holy Land the last six years, the interest in playing in Israel. That dream has come true.’’

Stoudemire, who played parts of five seasons with the Knicks after signing a $100 million contract, played last season with the Heat, but wanted to ceremonially retire as a Knick. He signed a non-guaranteed contract last week.

Stoudemire said he briefly talked to the Knicks about attending training camp, but admitted: “Their roster became pretty full.’’

Stoudemire would have stayed in the States for a deal with a title contender such as Golden State. He also said he broached talks about enlisting for another go-round with the Heat.

“We had a brief discussion with Miami. It didn’t go far,” Stoudemire told The Post after the press conference. “I wanted to compete. The reason I left to New York [at the end of the 2014-15 season], I was to trying to win a championship. I know my time was limited as far as my NBA career. I wanted to take advantage of my health. If that wasn’t the case, I would’ve stayed here in the rest of my career.’’

Knee issues derailed a surefire Hall of Fame career, but he still claims his legs feel good.

“Absolutely, I started 37 of the last 40 games for Miami. I was healthy all season,’’ Stoudemire said. “My body felt great. I wanted to retire on a healthy note from the NBA. I was able to accomplish that.’’

Hapoel Jerusalem owner Ori Allon and agent Happy Walters joined Stoudemire on the podium as he received his new red jersey with Hebrew lettering, while an Israeli flag hung by the podium.

Walter denied a report Stoudemire initially wanted to return to the Suns. He said they approached Phoenix two years ago but not this summer.

“They weren’t playoff teams,’’ Walters said of the NBA offers Stoudemire turned down. “He didn’t want to leave his family just to play. He wanted to keep the highest level, with a playoff team, or do this.’’

The Knicks fit the bill.

“They have a good team,’’ Stoudemire said. “I like what Phil [Jackson] did this year with the team, brought in very key pieces. Now it’s a matter of jelling and creating chemistry. I have faith they can have a really good year.’’

Derrick Rose is the new marquee addition as Stoudemire once was in 2010.

“My advice to Derrick Rose is to keep basketball first,’’ Stoudemire said. “Even though I indulged in the red-wine baths, Broadway shows, Met Opera and fashion shows, I indulged in the beautiful things New York had to offer. But my main focus was basketball and giving my heart and soul to the Knicks organization.’’

Allon called Stoudemire “the best player ever” to grace the Israeli League. Hapoel Jerusalem won its first Israeli League title in 2015, and the club believe Stoudemire’s addition will make it a contender to win the European championship.

“We already have a winning pedigree with the team,’’ Stoudemire said.

Stoudemire, who claims to have Jewish lineage on his mother’s side and follows some Jewish customs, said he has no intentions of signing with an NBA contender in March such as the Warriors if one comes calling.

“I locked in to win a [Euro] championship,’’ Stoudemire said. “If we go into the championship rounds, we’ll play into June.’’

Stoudemire leaves for Israel next week to find housing and schools before training camp opens in late August. He said he signed for two years with intentions of digging roots with his wife and two kids.

“I didn’t want to do a one-year situation because I would have to uproot my family again,’’ Stoudemire said.
