We report the identification of a very radio loud, narrow-line quasar, SDSS J094857.3+002225, discovered in the Sloan Digital Sky Survey (SDSS) early data release (EDR). With FWHM (Hβ)~1500 km/s and undetected [O III] λλ 4959, 5007 SDSS J094857.3+002225 is consistent with the conventional definition of narrow-line Seyfert 1 galaxies (NLS1s). Its strong optical Fe II emission [R₄₅₇₀≡f(FeIIλ4570)/f(Hβ)~1.59] is also typical of NLS1s. With a radio loudness RL≡(f_ν,4.85GHz/f_ν,B)≳1000 and radio power of P_4.85GHz~(3.6-5.2)x10²⁶ W Hz^–1, it is the first bona fide, very radio loud NLS1. The inverted radio spectrum and very high brightness temperature (≳10¹³ K) derived from variation of the radio flux suggest the presence of a relativistic jet beaming toward the observer in this NLS1.
