In a brief statement released on Monday, Hamlett said:"Recent reports of Thierry Henry joining the New York Red Bulls are false."
Unconfirmed reports over the last week have hinted that Henry, 41, would take over the reins at his former MLS club.
Red Bulls, under manager Chris Armas, have endured a difficult start to the season. After finishing top of the Eastern Conference last season, the club sits at 11th in the standings and have lost four for their first seven games.
After serving as assistant manager for Belgium at the 2018 World Cup, Henry had a disastrous three-month tenure at former club Monaco, winning four out of 20 games while in charge.
The ex-Arsenal and Barcelona striker played for NYRB from 2010-2014, scoring 51 goals in 122 MLS appearances.
