Jimmy "Yosser" Hughes is a fictional character from Alan Bleasdale's 1982 (written in 1978) television series Boys from the Blackstuff, set in Liverpool.

When the boys are swindled out of their savings in Middlesbrough, Yosser reacts particularly badly, showing the first signs of the nervous breakdown that would characterise his behaviour in the 1982 series.

The first episode of the series sees Yosser collecting social security from a Liverpool DHSS and making an unexpected appearance at an illegal building site, organised by a corrupt Irish contractor called Molloy.

In perhaps the most memorable episode of the series, Bleasdale shows the complete disintegration of Yosser's life as his children are taken into care (after he is beaten up in his own house by four policemen), he is made homeless and finally tries to drown himself in a lake.

Constantly trying to run the gauntlet of psychiatrists, social workers and creditors, Yosser makes numerous pathetic attempts to re-establish his identity and sense of self-worth, at one point gatecrashing a charity event to meet his apparent lookalike Graeme Souness.
