There will be NO public memorial service for Whitney Houston at the 18,000-seat Prudential Center in Newark, NJ ... because Whitney's family didn't want one -- this according to the City Mayor Cory Booker.

A rep for the Mayor's office tells TMZ, "The Houston family has no plans to set up a public viewing at the Prudential Center this Friday" -- despite several reports claiming there was going to be a massive public ceremony ... in addition to previously-scheduled private funeral arrangements.

The rep claims the family specifically asked the city NOT to plan a memorial event -- adding, "In compliance with the family’s wishes the city is not moving forward with any public ceremony."

The funeral is still set to take place this Saturday at New Hope Baptist Church
