We present the optical identification and spectroscopy of the host galaxy ofGRB 050826 at a redshift z = 0.296 +/- 0.001. Image subtraction amongobservations obtained on three consecutive nights, reveals a fading object 5hours after the burst, confirming its identification as the optical afterglowof this event. Deep imaging shows that the optical afterglow is offset by 0.4arcseconds (~1.76 kpc) from the center of its irregular host galaxy, which istypical for long-duration gamma-ray bursts. Combining these results with X-raymeasurements acquired by the Swift XRT instrument, we find that GRB 050826falls entirely within the subluminous, subenergetic group of long gamma-raybursts at low redshift (z < 0.3). The results are discussed in the context ofmodels that possibly account for this trend, including the nature of thecentral engine, the evolution of progenitor properties as a function ofredshift, and incompleteness in current gamma-ray burst samples.
