John Henry Dearle or J. H. Dearle (1860–1932) was a British textile and stained glass designer trained by Pre-Raphaelite artist and craftsman William Morris. Dearle designed many of the later wallpapers and textiles released by Morris & Co., and contributed background and foliage patterns to tapestry designs featuring figures by Edward Burne-Jones and others. Beginning in his teens as a shop assistant and then design apprentice, Dearle rose to become Morris & Co.'s chief designer by 1890, creating designs for tapestries, embroidery, wallpapers, woven and printed textiles, stained glass, and carpets. Following Morris's death in 1896, Dearle was appointed Art Director of the firm, and became its principal stained glass designer on the death of Burne-Jones in 1898.
