DPPIBa has been on top form for the Magpies this season, scoring 11 goals, and Newcastle manager Alan Pardew has said Ba would be sold if he did not remove the £7.5million release clause in his contract.
Arsenal are among a number of clubs linked with the 27-year-old, but Wenger said he had no plans to sign him.
"I like Demba Ba, yes," the Arsenal manager said ahead of his team's match against Newcastle.
"I don't think [this] is the right place to speak about that, because he plays against us.
"I wouldn't like to put Newcastle or us or him in an uncomfortable position. If you ask me, `Do we sign Demba Ba?', I say no."
