McCoy is a brand of pottery that was produced in the United States in the late 19th and 20th centuries.

In April 1910, Nelson McCoy (Senior), with help from his father (J. W. McCoy) and along with five stockholders, established the Nelson McCoy Sanitary and Stoneware Company in Roseville, Ohio. The pottery produced utilitarian stoneware and operated successfully until about 1918. They also bought, sold, and mined clay. At that time the pottery joined with eleven other stoneware potteries and formed the American Clay Products Company (ACPC), which was located in Zanesville, Ohio. All of the member potteries produced stoneware to be marketed by the new company. The ACPC produced sales catalogs of the wares that were produced, which purposely had no trademark, and had salesmen to advertise and take orders. The pottery orders received by the company were shared among the different potteries based on production capability, and the revenue received was proportionally distributed.
 
The ACPC thrived until January 1926, at which time the company was liquidated. The demise of the company released the former member potteries to once again become independent and they became in direct competition with one another. Also around this time the demand for utilitarian stoneware was beginning to decrease.
 
The rise
In order to re-establish its own identity, and also to reflect the changing times, the Nelson McCoy Sanitary and Stoneware Co., by 1929, had changed its name to the Nelson McCoy Sanitary Stoneware Co. Additionally, it was around this time that the company began the practice of marking its wares. No evidence has been found that the company had ever marked any of its wares prior to this time. In 1933, in response to a further decreased demand for food and sanitary wares, and an increased demand for decorative pieces, the name of the pottery was changed again. The pottery became simply, the Nelson McCoy Pottery Co.
 
The decline
Nelson McCoy, Sr., Nelson Melick, and later Nelson McCoy, Jr., in turn, operated the pottery for 57 years until it was sold in 1967 to the owners of the Mt. Clemens Pottery Co., although Nelson McCoy, Jr., remained as president of the pottery. After about seven years of operation the Lancaster Colony Corporation purchased the pottery in 1974. In 1981 Nelson McCoy, Jr., retired. In 1985, the pottery was sold once again, this time to Designer Accents of New Jersey. Some months earlier, Designer Accents had acquired two other potteries, Holiday Designs of Sebring, Ohio, and their Sebring Studios division. Designer Accents also acquired the Sunstone Pottery of Cambridge, Ohio.
 
All production at these potteries was moved to the Nelson McCoy Pottery. The production of some of the wares formerly produced was continued, and other wares were discontinued. The ware formerly produced by Holiday Designs, being lower priced items, was discontinued, while the higher priced wares from Sebring Studios were continued for some time. The ware produced under the name Sebring Studios was marked with only a style number.
 
Selected items previously made by the McCoy pottery, and some newly designed items, were marketed by Designer Accents under the name Nelson McCoy Ceramics. Some of these items have the familiar McCoy name on them. The Floraline line with its distinctive mark, first produced by the Nelson McCoy Pottery in 1960, was also continued.
 
Designer Accents operated for about five years until closing in late 1990. The portion of the pottery containing the offices burned in the fall of 1991
 
The McCoy trademark
The United States Patent and Trademark Office lists three individuals or companies that have applied for a Trademark using the name "McCoy" for use on pottery.
 Designer Accents, Inc., the final owner of the Nelson McCoy Pottery Company, filed the first of these applications on June 7, 1989. In the fall of 1990, the pottery closed. The application was canceled on December 20, 1997.
 On August 31, 1992, Roger Jensen from Rockwood, Tennessee, applied for use of the name "McCoy" as a trademark on pottery he made. The application stated that the first use of the proposed trademark was in January 1991. The application was canceled on May 25, 1999.
 A year before the Jensen application was canceled, Designer Accents, Inc. reapplied. This was on August 19, 1998. This application was abandoned on July 31, 2000.
 On October 28, 1999, Rosella Martin of Century, Florida, made application to use the name "McCoy" on numerous types of pottery she produced. On May 24, 2001, this application was abandoned.
