In reply to a written parliamentary question tabled by deputy Tommy Broughan, Minister Frances Fitzgerald confirmed the phones were seized by prison authorities between January 1 and February 8.
According to the figures, a total of 96 phones were seized at prisons across the country during the same time period.
Meanwhile, Ms Fitzgerald revealed that 18 phones were seized at Limerick Prison during all of 2014 - down from 56 in 2013.
