The former Tonight Show host is believed to be attracted to the idea as it will allow him to talk directly to fans, a source told The Hollywood Reporter.
The insider revealed that while details are still in their early stages, O'Brien could perform live at a string of US venues, including college campuses, before heading to Europe.
A spokeperson for O'Brien has since declined to comment on the reports.
As part of O'Brien settlement with NBC in the wake of his exit from his primetme talk show, the 46-year-old is banned from making television appearances until September, although the agreement does not prevent him from performing live.
The tour is likely to be followed with a new show for O'Brien, who quit Tonight last month when the network attempted to shift him to a later slot. Possibilities include Fox, which has previously expressed interest.
