Palace have been struggling for goals in recent weeks, failing to score in their last three games, and Pardew is keen to bolster his attacking options in January.
Warnock, who briefly served as interim QPR caretaker manager earlier this season, suggested to Talksport earlier this week that Austin would be the perfect solution to Palace's scoring problems, but Pardew dismissed the idea and made it clear he would not welcome any more.
"Neil Warnock was the manager here and he didn't do very well so I am not really interested in his opinion," Pardew said. "Charlie Austin is of no interest to us."
Pardew revealed that Palace are currently working on deals for a couple of players but said any targets mentioned in the media have been wide of the mark.
"I've seen all the names that have been linked with us and not one of them is true," he said. "Somebody's giving out some false information.
"It would be stupid of me to say who is in the frame. We are looking at one or two names, but the names that have been linked with us are not them."
Pardew admitted he is anxious to improve his attacking options but was adamant he will not bring in a player for the sake of it.
"I just want them to be good enough to play for Crystal Palace," said the former Newcastle United boss. "The bottom line is that the market is not big.
"With the strikers I have here, what is the point of bringing in strikers that are not better than the ones I have already got?
"Dwight Gayle, Marouane Chamakh, Connor Wickham, Bakary Sakho to a degree, Yannick Bolasie - you can give me a list after if you can find any better than that.
"This market is going to be very difficult, not just for me but for all the Premier League teams. If you ask any Premier League manager if he would like another striker the answer is yes. Can you afford to have one with the quality that is available? I don't know."
