We report the discovery of a galaxy cluster at z = 1.41. ISCS J143809+341419was found in the Spitzer/IRAC Shallow Survey of the Bootes field in the NOAODeep Wide-Field Survey carried out by IRAC. The cluster candidate was initiallyidentified as a high density region of objects with photometric redshifts inthe range 1.3 < z < 1.5. Optical spectroscopy of a limited number of objects inthe region shows that 5 galaxies within a ~120 arcsec diameter region lie at z= 1.41 +/- 0.01. Most of these member galaxies have broad--band colorsconsistent with the expected spectral energy distribution of apassively--evolving elliptical galaxy formed at high redshift. The redshift ofISCS J143809+341419 is the highest currently known for aspectroscopically-confirmed cluster of galaxies.Comment: Accepted for publication in The Astrophysical Journal Letters; 5 pages and 5 figure
