An agriculture ministry or department of agriculture is a ministry or other government agency charged with agriculture. The ministry is often headed by a minister for agriculture.

Specific duties may relate to regulation, promotion, agricultural research, price supports and agricultural subsidies, plant diseases and invasive species.Some ministries have additional responsibilities in related policy areas such as forestry and fisheries; rural affairs; food and food quality, security, and safety; and consumer protection. In some countries, agriculture ministries are responsible for matters relating to the environment as well while others assign that duty to a separate environment ministry.

Gerry Ritz, PC, MP (born August 19, 1951) is Canada's Agriculture minister and a Canadian Member of Parliament for Battlefords—Lloydminster, a largely rural riding in Saskatchewan. Born in Delisle, Saskatchewan, he was elected as the Reform Party candidate in the 1997 general election, and then re-elected with the Canadian Alliance in the 2000 election and the Conservative Party of Canada in the 2004 election. Ritz has been the vice-chair of the House of Commons Agriculture Committee since 2002. He was appointed Secretary of State for small business and tourism in the Harper government on January 4, 2007. On August 14, 2007, Ritz was promoted to the Cabinet as Minister of Agriculture and Agri-Food replacing Chuck Strahl.

Prior to his political career, Ritz worked as a farmer at the family farm for over 20 years and owned a contracting business company.

Since before he was appointed as Agriculture Minister, Ritz has campaigned to allow farmers to sell their barley in the open market, rather than exclusively through the Canadian Wheat Board (CWB). Many farmers who want to seek the highest possible price oppose the monopoly of the board, while others believe that eliminating the board would ultimately have the effect of driving crop prices downward because of increased competition between individual farmers and by competition between marketing companies as was proven by the loss of the Australian Wheat Board in Australia in 2009-2010.^{[citation needed]} The previous Agriculture Minister, Chuck Strahl, had also proposed ending the monopoly.
