We report the localization of the Integral-discovered X-ray transient IGR J16283-4838. IGR J16283-4838 was observed by Swift on April 13th at 14:01:56 UTC for 2.5ks as a Target of Opportunity observation. We have performed a preliminary analysis of the Swift-XRT data and have found a uncatalogued X-ray source at the following coordinates: RA(J2000): 16:28:10.7, Dec(J2000): -48:38:55. We estimate an uncertainty of about 5 arcseconds radius (90% containment). This position is 91 arcseconds from the INTEGRAL position reported in ATEL #456. The source is highly absorbed with no detected emission below 1.5 keV.
