Joseph Jenkins was a Welsh itinerant labourer in late 1800s Victoria.

Exceptional for a labourer at the time, Jenkins had a high level of literacy and kept detailed daily diaries for over 25 years, resulting in one of the most comprehensive accounts of early Victorian working life.

Itinerant labourers of the 1800s, or 'swagmen', have become mythologised in Australian cultural memory, and so these diaries provide a wonderful source of information about the life of a 'swagman'. They also provide a record of the properties and districts Jenkins travelled to, particularly around the Castlemaine and Maldon area.

The diaries were only discovered 70 years after Jenkins' death, in an attic, and were in the possession of Jenkins’s descendants in Wales until recently, when they were acquired by the State Library of Victoria in 1997.
