Highly redshifted 21 cm neutral hydrogen emission from the Epoch of Reionization (EOR) is a unique cosmological probe, and planned low frequency radio observations could revolutionize our understanding of galaxy and structure formation and the emergence of the first luminous objects.  However, EOR observations are complicated by strong foreground contamination and stringent instrumental requirements.  In this talk, I will review the observational signatures of the Epoch of Reionization and how the faint 21 cm emission can be extracted from the foreground signals, and describe the observations my colleagues and I are undertaking with the Very Large Array (VLA) and the Mileura Widefield Array - Low Frequency Demonstrator (MWA-LFD).
