A 29.3deg^2 region surrounding the north ecliptic pole (NEP; R.A.=18h00m, Dec.=+66d30m) was mapped with the Very Large Array at 1.5GHz to support the deepest portion of the ROSAT all-sky soft X-ray survey. The resulting VLA-NEP survey catalog contains 2435 radio sources with flux densities in the range of 0.3-1000mJy, including over 200 fainter than 1mJy. The 28 fields of the inner 1.5deg have noise levels sigma ~=60uJy, and the 85 fields centered between 1.5deg and 3.0deg from the NEP have sigma ~=120uJy. The typical spatial resolution is 20" HPBW, and most positions are accurate to <2". Approximately 6% of the sources are found to be extended with size >30". We have compared the VLA-NEP catalog with four other radio catalogs made at lower resolution, as well as with the NASA Extragalactic Database and find counterparts for ~18% of the VLA-NEP objects. The normalized, differential radio source count is in agreement with the previous studies. Between 1 and 150mJy the slope of the logN-logS relation is 0.68+/-0.03. (2 data files).
