James Glennister "Jim" Cox is a former Tasmanian Labor politician and member of the Tasmanian House of Assembly in the electorate of Bass. He was first elected in the 1989 election. He was defeated in the 1992 election and re-elected in the 1996 election, holding the seat until his retirement in 2010.
In 1989, Tasmanian media magnate Edmund Rouse, Chairman of Gunns, attempted to bribe Cox with $110,000 to cross the floor of parliament in an attempt to prevent Labor forming government in alliance with the five Green Independents, and attempting to secure the return of the pro-logging Liberal Party government of Robin Gray. Cox reported the bribery attempt to police, and ultimately Rouse served 18 months in jail.
Cox was re-elected in the 2006 election, receiving 15.3% of first preferences, a decrease compared to his previous result of 17.5% in the 2002 election.
Before entering Parliament, Cox co-hosted the The Saturday Night Show on TNT-9 with Graeme Goodings and was a radio announcer in northern Tasmania. Cox won Logie Awards for most popular male on Tasmanian television in 1979 and 1981.
