The politician, who won her seat standing for UKIP but subsequently left and founded the We Demand A Referendum Now party, will be giving a speech to the club on Wednesday.
The Rotarians will be able to question Nikki on any aspect of her role and to debate the issues surrounding EU membership.
Nikki Sinclaire MEP said: "I’m looking forward to meeting with the Rotarians and hearing all about the great work they are doing in their local community.
"Many people do not even know who their local MEP is, so I’m looking forward to giving the Rotarians a chance to quiz me about my work, achievements and political beliefs."
She added: "We need to start the debate on EU membership. I hope that my speech will inspire debate within the members and their wider network of friends and family. It is vital that we start the debate now so that political leaders do not sweep the issue under the carpet."
The Rotary Club of Halesowen and Rowley Regis meet every Wednesday at Halesowen Golf Club at 12.30pm.
