The long, bright gamma-ray burst GRB 070125 was localized by the Interplanetary Network. We present light curves of the prompt gamma-ray emission as observed by Konus-Wind, RHESSI, Suzaku WAM, and Swift BAT. We detail the results of joint spectral fits with Konus and RHESSI data. The burst shows moderate hard-to-soft evolution in its multipeaked emission over a period of about 1 minute. The total burst fluence as observed by Konus is 1.79x10^–4 ergs/cm2 (20 keV-10 MeV). Using the spectroscopic redshift z=1.548, we find that the burst is consistent with the ``Amati'' E<sub>peak,i</sub>-E<sub>iso</sub> correlation. Assuming a jet opening angle derived from broadband modeling of the burst afterglow, GRB 070125 is a significant outlier to the ``Ghirlanda'' E_peak,i-E_γcorrelation. Its collimation-corrected energy release, E_γ=2.5x10⁵² ergs, is the largest yet observed.
