We present spectroscopic observations of ESO 184-G82, the host
galaxy of GRB 980425/SN 1998bw, and six galaxies in its field. A
host redshift of 
is derived, consistent with
that measured by Tinney et al. (1998, IAU Circ., 6896). Redshifts are
obtained for the six surrounding galaxies
observed. Three of these galaxies lie within 11 Mpc of each
other, confirming the suggestion that some of these galaxies form
a group. However, all of the field galaxies observed lie at
significantly greater distances than ESO 184-G82 and are
therefore not associated with it. The host galaxy of
GRB 980425/SN 1998bw thus appears to be an isolated dwarf
galaxy and interactions with other
galaxies do not seem to be responsible for its star formation.
Key words: galaxies: individual: ESO 184-G82 / gamma rays: bursts / supernovae: individual: SN 1998bw
