Abstract
We investigate the prospects for discovering blazars at very high redshifts z∼ 5. We find that the Fermi may discover a few blazars up to z∼ 6 in the entire sky during its 5-yr survey. We further discuss how such high-redshift blazar candidates may be efficiently selected in the future Fermi data.
