An aid agency is an organisation dedicated to distributing aid. Many professional aid organisations exist, both within government (e.g. AusAID, USAID, DFID, EuropeAid, ECHO), between governments as multilateral donors (e.g. UNDP) and as private voluntary organizations (or non-governmental organisations, (e.g. ActionAid, Oxfam, World Vision). The International Committee of the Red Cross is unique in being mandated by international treaty to uphold the Geneva Conventions.

Aid can be subdivided into two categories: humanitarian aid (emergency relief efforts, e.g. in response to natural disasters), and development aid (or foreign aid), aimed at helping countries to achieve long-term sustainable economic growth, with the aim of achieving poverty reduction. Some aid agencies carry out both kinds of aid (e.g. EcoCARE Pacific Trust and ADRA), whilst others specialise (e.g. Red Cross, humanitarian aid; War on Want, development aid).

Mark Harvey (born 11 June 1965) is a former Australian rules football player who played for the Essendon Football Club. He played 206 games from 1984 to 1997, kicking 190 goals, and was assistant coach at Essendon from 1998 to 2005. He was senior coach of the Fremantle Football Club from 2007 till 2011.

Harvey was originally known as a skilful forward, playing that role in the 1984 and 1985 premiership sides, including kicking four goals in the 1985 premiership win. However, injuries in his later career (particularly to his ankles) meant he was used more as a defender, which reduced the stress on his body. In his role as a defender he often played as center half-back against much taller opponents, making up for his lack of height with his aggressive attack on the football.

Harvey finished in the top five of the Essendon best-and-fairest on four occasions, winning the award in 1992. He was named in the All Australian Team in 1985 and 1993; he also played in premiership sides both those years as well as in 1984. He was also the side's leading goalkicker for the 1985 season, an unusual feat for a medium-sized forward in a premiership winning team. In 2002 he was named as the 18th greatest player to play for the club in the "Champions of Essendon" list.
