The Livery Companies are 108 trade associations in the City of London, almost all of which are known as the "Worshipful Company of" the relevant trade, craft or profession. The medieval Companies originally developed as guilds and were responsible for the regulation of their trades, controlling, for instance, wages and labour conditions. Until the Protestant Reformation, they were closely associated with religious activities, notably in support of chantry chapels and churches and the observance of ceremonies, notably the mystery plays.

Livery Companies er betgnelsen på en rekke (i alt over 100) gamle engelske yrkesorganisasjoner. Organisasjonene sprang ut av middelalderens laug, og tjente til å beskytte de ulike profesjonene ved å regulere adgangen til yrket, organisere fagopplæringa, fastsette lønninger osv.
