An alderman is a member of a municipal assembly or council in many jurisdictions founded upon English law. The term may be titular, denoting a high-ranking member of a borough or county council, a council member chosen by the elected members themselves rather than by popular vote, or a council member elected by voters.

The title is derived from the Old English title of ealdorman, literally meaning "elder man", and was used by the chief nobles presiding over shires.

Many local government bodies used the term "alderman" in Australia. As in the way local councils have been modernised in the United Kingdom and Ireland, the term alderman has been discontinued in a number of places. For example, in the State of Queensland before 1994, rural "shires" elected "councillors" and a "chairman", while "cities" elected a "mayor" and "aldermen". Since 1994, all local and regional government areas in Queensland elect a "mayor" and "councillors." (The Brisbane City Council has always had a "Lord Mayor"). An example of the use of the term alderman was in the City of Adelaide. Aldermen were elected from the electors in all the wards.

Charles Joseph "Joe" Clark, PC CC AOE (born June 5, 1939) is a Canadian statesman, businessman, and university professor, and former journalist and politician. He served as the 16th Prime Minister of Canada, from June 4, 1979, to March 3, 1980.

Despite his relative inexperience, Clark rose quickly in federal politics, entering the House of Commons in the 1972 election and winning the leadership of the Progressive Conservative Party in 1976. He came to power in the 1979 election, defeating the Liberal government of Pierre Trudeau and ending sixteen continuous years of Liberal rule. Taking office the day before his 40th birthday, Clark is the youngest person to become Prime Minister. His tenure was brief as he only won a minority government, and it was defeated on a motion of non-confidence. Clark subsequently lost the 1980 election and the leadership of the party in 1983.

He returned to prominence in 1984 as a senior cabinet minister in Brian Mulroney's cabinet, retiring from politics after not standing for re-election for the House of Commons in 1993. He made a political comeback in 1998 to lead the Progressive Conservatives before its dissolution, serving his final term in Parliament from 2000 to 2004. Clark today is recognized as a distinguished scholar and statesman, and serves as a university professor and as president of his own consulting firm.
