Manufacturing Grocers' Employees' Federation of Australia (M.G.U.) was an Australian trade union existing between 1906 and 1988. The union was first established as the Federated Candle, Soap, Soda & Starch Employees' Union of Australia, before changing its name in 1914. The union represented workers employed in manufacturing grocers' sundries and non-edible grocery products, particularly in the southern states of South Australia and Victoria. In 1988 the union amalgamated with the Federated Millers and Mill Employees' Union to form the Federated Millers and Manufacturing Grocers Employees' Association of Australia, which in turn merged with a number of unions to form the National Union of Workers.
