We derive the extinction toward SN 2014J, a Type Ia supernova in M82, as a function of wavelength from the far ultraviolet to the near infrared by modeling the observed color excesses in terms of a mixture of silicate and graphite. With Av ≈ 1.9 mag and RV ≈ 1.7-1.8, the derived extinction law differs substantially from those of the Galaxy and the Magellanic clouds.
