D'Andrea is an American guitar pick and accessories maker with roots in 1922, when Italian immigrant Luigi D'Andrea began stamping heart-shaped plectrums out of celluloid in New York City. The company is widely credited with producing the first plastic guitar pick and went on to develop dozens of pick shapes in celluloid and tortoise shell, including the #351 silhouette that became the de facto standard teardrop shape used across the industry.

The brand's catalog covers celluloid picks, the Pro Plec line, thumb and finger picks, pickguards, guitar straps, and instrument care products. D'Andrea also operates as a plastics supplier and private-label manufacturer, producing picks for retailers and other major pick brands. Beyond stock shapes and gauges, the company is known in the trade for custom and promotional pick printing.

Now a division of Delmar Products, Inc. and based in Berlin, Connecticut, D'Andrea continues to produce its historic lines alongside newer signature and novelty designs. Its long catalog of shapes, gauges, and materials has made it a reference point for players chasing specific vintage pick feels, and its celluloid formulations remain a staple among guitarists who prefer that classic material over modern polymers.

D'Andrea has 20 products cataloged on Equipboard, including Picks & Pick Holders, Straps & Strap Locks, and Slides. Their gear is featured by 10 artists, with the strongest followings in Rock, Pop, and Latin. Notable users include David Gilmour, Jimi Hendrix, and Álvaro Henriquez.
