  In this paper, we have used the Gaia's Data Release-3 (DR3) data to study an
intermediate-age open cluster Berkeley 27 (Be 27). A total of 131 most probable
cluster members are picked within the cluster's radius based on the membership
probability ($> 80\%$). The cluster's radius was estimated as 3.74 arcmin. The
mean proper motion (PM) of Be 27 was determined to be ($\mu_{\alpha}
cos{\delta}$, $\mu_{\delta}$)= ($-1.076\pm0.008$,
$0.152\pm0.007$)~mas~yr$^{-1}$. The blue straggler stars (BSS) of the cluster
were found to be located in the central region. Theoretical isochrones of
metallicity Z$_{metal}$= 0.008 were compared to the color-magnitude diagram
(CMD) of Be 27. As a result, a heliocentric distance of 4.8$\pm$0.2 kpc and log
(age) = 9.36$\pm$0.03 were determined for Be 27. The Galactic orbits are
derived using the Galactic potential model which demonstrate that Be 27 follows
a circular path around the Galactic center. The cluster does not seem to be
affected much by the tidal forces from the Galactic thin disk.
