Marcus Brothers Textiles, Inc. is a historic family-owned textile company founded in 1906 by six brothers from the Marcus family. Specializing as a converter and importer of craft, quilting, and apparel-related products, the company developed a wide range of textile products, including collections of wools, soft fabrics, and other materials used in sewing, quilting, and apparel industries. Over its more than century-long history, it became known for brands like Marcus Fabrics, which catered to retail divisions and enthusiasts in the fabric and crafting sectors. The company was headquartered in New York City and maintained operations focused on manufacturing and distribution within the textile trade.

In addition to its commercial activities, Marcus Brothers Textiles served a unique role as the physical headquarters for the volunteer operations of the Central Fund of Israel (CFI), an organization affiliated with the company through institutional ties. This connection highlights the Marcus family's broader involvement in philanthropic and advocacy networks supporting Israeli causes. The company's leadership included figures like Dell 'Olio, who served as president of the Retail Division and was a noted sewing and fabric enthusiast, contributing to its reputation in the creative fabric community.

Public records indicate that Marcus Brothers Textiles may have ceased operations, with its New York location listed as closed. Despite this, its legacy endures in the textile industry through archived products and brand references on various fabric retailer sites. The company's evolution from a small family enterprise to a key player in specialty textiles underscores its influence in niche markets, while its association with CFI points to intersecting business and ideological networks.
