We report on the confirmation of a transiting giant planet around the
relatively hot (Teff = 6801 $pm$ 56 K) star HD2685, whose transit signal was
detected in Sector 1 data of the TESS mission. We confirmed the planetary
nature of the transit signal by using Doppler velocimetric measurements with
CHIRON, CORALIE and FEROS, as well as photometric data with CHAT and LCOGT.
From the photometry and radial velocities joint analysis, we derived the
following parameters for HD2685 $b$: $P$=4.12692$pm$0.00004 days, M$_P$=1.18
$pm$ 0.09 $M_J$ and $R_P$=1.44 $pm$ 0.01 $R_J$. This system is a typical
example of an inflated transiting Hot-Jupiter in a circular orbit. Given the
host star apparent visual magnitude ($V$ = 9.6 mag), this is one of the
brightest known stars hosting a transiting Hot-Jupiter, and a good example of
the upcoming systems that will be detected by TESS during the two-year primary
mission. This is also an excellent target for future ground and space based
atmospheric characterization as well as a good candidate for measuring the
projected spin-orbit misalignment angle via the Rossiter-McLaughlin effect.
