Hawaii's 2nd congressional district is a congressional district in the U.S. state of Hawaii. The district encompasses all rural and most suburban areas that are part of the City and County of Honolulu, which covers all of the island of Oahu. While the urban areas of Oahu are part of the Hawaii's 1st Congressional District, the 2nd Congressional District includes all of the Windward, North Shore, Central, and Leeward regions of Oahu. It also includes the entire state outside of Oahu. This includes the areas located in the counties of Kauai (which includes the islands of Kaua i, Ni ihau, Lehua, and Ka ula), Maui (which consists of the islands of Maui, Kahoolawe, Lānai, Molokai except for a portion of Molokai that comprises Kalawao County, and Molokini) and Hawaii coextensive with the Island of Hawai i, often called "the Big Island." The district spans 331 miles. The most populous city entirely within the district is Hilo. Major segments of the economy include tourism, ranching, and agriculture, especially pineapple and sugarcane cultivation.
The district is currently represented by Democrat Mazie Hirono.
