In the music industry, Trade Mark of Quality (abbreviated TMOQ or TMQ) was a bootleg record label based in Los Angeles, California, during the late 1960s and early 1970s. The label was responsible for many underground records of Bob Dylan, Pink Floyd, Led Zeppelin, Jefferson Airplane, Devo, Grateful Dead, The Beatles, Frank Zappa, The Rolling Stones, The Who and many other rock artists of the era.

Trade Mark of Quality was established in 1970 by "Dub" Taylor and Ken Douglas. They were quality-conscious perfectionists who pressed many of their albums on colored, virgin vinyl, and possibly the first bootleggers to start producing printed picture covers, and later color picture covers, rather than paper inserts. Taylor and Douglas had released several albums under different names before settling on "Trade Mark of Quality" in 1969, the first being Great White Wonder by Bob Dylan. According to Douglas, Taylor recorded several of TMOQ's releases himself, including the Rolling Stones' Live'r Than You'll Ever Be and Led Zeppelin's Live On Blueberry Hill. TMOQ frequently released its albums with cover art by William Stout.
