We present  UBVRI  CCD photometry and optical spectra of the type Ia supernova SN 2003hx which appeared in the galaxy NGC 2076, obtained till ∼ 146 d after the epoch of  B ‐band maximum. The supernova reached at maximum brightness in  B  band on JD 245 2893 ± 1.0 with an apparent magnitude of 14.92 ± 0.01 mag which was estimated by making template fits to the light curves. SN 2003hx is an example of a highly reddened supernova with   E ( B − V ) = 0.56 ± 0.23 . We estimate   R   v  = 1.97 ± 0.54  which indicates the small size of dust particles as compared to their galactic counterparts. The luminosity decline rate is  Δ m  15 ( B ) = 1.17 ± 0.12  mag and the absolute  B ‐band magnitude obtained from the luminosity versus decline rate relation (Phillips et al. 1999) is   M   B   max =−19.20 ± 0.18  mag. The peak bolometric luminosity indicates that  ∼0.66 M ⊙   mass of  56 Ni was ejected by the supernova. The spectral evolution indicates the supernova to be a normal type Ia event.
