  In this study, we have used the {\it Gaia} Third Data Release (Gaia DR3) to
investigate an intermediate-age open cluster Collinder 74. Taking into account
the stars with membership probabilities over 0.5 and inside the limiting radius
of the cluster, we identified 102 most likely cluster members. The mean
proper-motion components of Collinder 74 are estimated as ($\mu_{\alpha}\cos
\delta, \mu_{\delta})=(0.960 \pm 0.005, -1.526 \pm 0.004$) mas yr$^{-1}$. We
detected previously confirmed four blue straggler stars which show flat radial
distribution. Colour excess, distance, and age of the cluster were estimated
simultaneously by fitting {\sc PARSEC} isochrones to the observational data on
{\it Gaia} based colour magnitude diagram. These values were derived as
$E(G_{\rm BP}-G_{\rm RP})=0.425\pm 0.046$ mag, $d=2831 \pm118$ pc and $t=1800
\pm 200$ Myr, respectively. The mass function slope was estimated as $\Gamma =
1.34 \pm 0.21$ within the mass range $0.65\leq M/ M_{\odot}\leq 1.58$ which is
well matched with that of Salpeter. Stellar mass distribution indicated that
the massive and most likely stars are concentrated around the cluster center.
The total mass of the cluster was found to be 365 $M/M_{\odot}$ for the stars
with probabilities $P>0$. Galactic orbit integration shows that the Collinder
74 follows a boxy pattern outside the solar circle and is a member of the
thin-disc component of the Galaxy.
