The Department of Environment and Natural Resources (Filipino: Kagawaran ng Kapaligiran at Likas na Yaman) is the executive department of the Philippine government responsible for governing and supervising the exploration, development, utilization, and conservation of the country's natural resources.

The Department of Environment and Natural Resources was first established on January 1, 1917 as the Department of Agriculture and Natural Resources (DANR) through the enactment of Act No. 2666 by the Philippine Commission, otherwise known as "An Act to Re-organize the Executive Department of the Government of the Philippine Islands," on 18 November 1916. In 1932, the DANR was reorganized into the Department of Agriculture and Commerce (DAC).

In 1947, a reorganization act changed the DAC back to the Department of Agriculture and Natural Resources. The Natural Resources arm of the DANR was finally spun off on May 17, 1974 as the Department of Natural Resources. On January 30, 1987, the Ministry was reorganized into the Department of Environment, Energy and Natural Resources by Executive Order No. 131 and was finally reorganized into the Department of Environment and Natural Resources by Executive Order No. 192 on June 10, 1987. Currently, the DENR is working on a large-scale reforestation of Davao.

Jose Livioko Atienza, Jr. (born August 10, 1941), commonly known by his nickname Lito Atienza, is the former city mayor of Manila and former secretary of the Department of Environment and Resources. He stepped down as mayor of Manila on June 30, 2007, after serving a three-year three-term limit for local government executives set by the Philippine Constitution of 1987. He currently hosts GMA Network's Maynila since 1999.

Atienza was born in the district of San Andres Bukid, four months before the outbreak of World War II. Atienza’s father, Jose J. Atienza, Sr., was a distinguished public servant to three Philippine presidents. An uncle, Herminigildo Atienza, was a World War II guerrilla leader and after the war was appointed Military Mayor of Manila by Gen. Douglas McArthur himself. Another uncle, Rigoberto Atienza, became Chief of Staff of the Philippine Armed Forces in the 1960s during the term of President Diosdado Macapagal. A third uncle, Arturo, became a renowned lawyer. The four brothers were all members of the Hunters resistance against the Japanese occupation during World War II.
