The Celtic forward has been in prolific form this season, sparking suggestions of an England call-up and a move to Anfield, with the Reds suffering a shortage of attacking talent
Fabio Borini is out for up to three months for the Reds, and with Andy Carroll on loan at West Ham manager Brendan Rodgers has only one senior striker available in Luis Suarez.
Hooper has nine goals in all competitions for the Hoops, prompting talk of an England call-up, but Lennon insists his star striker is going nowhere.
"It is speculation," said Lennon. "It wouldn't surprise me if there are a number of clubs in for Gary because of the way he is but I would poo-poo that [Liverpool link].
"We are still in negotiations at the minute and I don't think we are too far away.
"There will be interest but [he's] going nowhere. If there are offers coming in, they will have to pay what we feel the valuation is."
The Celtic boss is also hopeful midfielder Victor Wanyama will sign a new deal to prolong his stay in Glasgow.
He said: "We are hoping to meet his representative again next week.
"He has been offered a new contract. We don't have to offer him a new contract, his [current one] still has a couple of years to run but we feel it is a reward for performances he has put in since he came in the door.
"Whether his agent feels it is sufficient - that's what negotiations are all about.
"Hopefully we can come to a conclusion about that as well."
