"The six paintings feature in a Glasgow exhibition by Peter Howson.
Howson, who has battled drug and alcohol addiction, said the pictures were intended to act as a warning against drugs.
A spokesman for Doherty said: "Peter Howson has never met Pete as far as I am aware, so I don't know where he's getting hi"s inspiration from."
He added: "We have not seen the drawings and I don't see how Peter knows that much about Pete's lifestyle."
Howson became established in the 1980s as one of the "New Glasgow Boys", a clique of painters concerned with portraying social issues.
He is also known for his distinctive figurative paintings of the Bosnian war and the singer Madonna.
Howson said: "Pete Doherty is someone who has really interested me over the last few months.
"His spiral downwards reminds me of what I went through myself and I can identify with the way he is acting.
"Me wanting to paint him dead was pointing the finger at him and saying 'You can influence a whole generation'.
"He could, if he wanted to, become the right kind of hero."
