Lang, who plays Brooke Logan on B&B, will appear as herself, passing through Erinsborough, joined on screen by Colette Mann (Neighbours' Sheila Canning).
“I am so excited to be on the longest-running television series in Australia, with so much history and drama," Lang said in a statement. "I'm looking forward to bringing some of The Bold and The Beautiful flair to the show.”
Neighbours producer Jason Herbison added: "Katherine is one of the queens of soap in the US and we are thrilled to have her appear in Neighbours. We will certainly give her the Ramsay Street red carpet experience."
Neighbours has a long history of celebrities appearing as themselves on the soap.
Lang's appearance will air in March 2016.
