Denis Wick Products is a British manufacturer of brass mouthpieces, mutes, and accessories based in Poole, United Kingdom. The company was founded in 1968 by Denis Wick (1931–2025), the longtime principal trombonist of the London Symphony Orchestra, who began crafting mouthpieces and mutes to address problems he and fellow players were experiencing. What started as a personal project — with early trombone mutes famously auditioned for composer Benjamin Britten — grew into a firm supplying professional and student brass players worldwide.

The catalog covers mouthpieces and mutes for trumpet, cornet, flugelhorn, French horn, tenor horn, trombone, baritone, euphonium, and tuba. Signature product lines include the Classic and Heritage mouthpiece ranges, along with straight, cup, practice, and wooden mutes that became standards in orchestral and brass band settings. The original trombone mouthpiece design, informally labelled the 'A,' remains a reference point for the brand.

Denis Wick products are widely used across symphony orchestras, film score sessions, brass bands, and military bands, and the company maintains an extensive artist roster of classical and brass band soloists. The firm received the Queen's Award for Enterprise in International Trade in 2013.

Denis Wick has 3 products cataloged on Equipboard, including Mutes.
