The singer, whose hits include "...Baby One More Time" and "I'm a Slave 4 U," has been playing a series of shows this summer in Europe, including in Britain, France and Sweden.
The July 24 show in Warsaw was canceled because of a contractual dispute that could not be resolved, a statement released by her publicist said Wednesday.
She refused to elaborate.
David Froffman, PR manager for AEG Live in the UK, declined to comment.
An official Web site devoted to Spears' Polish stop, http://www.britneykoncert.pl, said ticket holders would be reimbursed.
The Warsaw concert was to have been Spears' second-to-last show in Europe before the "Circus" tour returns to the United States. She is scheduled to play at the 02 Arena in the German capital, Berlin, on July 26.
Bocianowicz said tickets to the Warsaw concert "had been selling, but I can't say that the concert was sold out."
The 27-year-old "Womanizer" singer is scheduled to embark on an Australian tour in November after performing a series of shows in the U.S. and Canada.
