Yoshihiko Noda (Japanese: 野田 佳彦, Hepburn: Noda Yoshihiko; born 20 May 1957) is a Japanese politician. He is the current leader of the Constitutional Democratic Party of Japan (CDP), and has been a member of the House of Representatives since 2000. He served as the Prime Minister of Japan from 2011 to 2012.

Noda entered politics in 1993 as a member of the now-defunct Japan New Party. In 1996, he joined the Democratic Party of Japan (DPJ). After the DPJ won control of the Diet in 2009 general election, Noda was named a senior vice minister of finance in the cabinet of Prime Minister Yukio Hatoyama, and in 2010, was named minister of finance in the cabinet of Prime Minister Naoto Kan. Following Kan's resignation as prime minister, Noda won the ensuing leadership election and was appointed prime minister on 2 September 2011.

Following a severe loss for the DPJ in the December 2012 general election, Noda announced his resignation as party leader, triggering a leadership election that was won by Banri Kaieda. Noda was succeeded as Prime Minister by Shinzo Abe, President of the Liberal Democratic Party, on 26 December 2012.

As the DPJ underwent mergers and reorganizations, Noda left to sit as an independent politician. In 2021, Noda joined the CDP, the primary successor to the DPJ. In 2024, Noda successfully stood for the CDP's party presidential election, defeating incumbent leader Kenta Izumi and former leader Yukio Edano. Weeks after assuming the presidency of the party, the 2024 Japanese general election was announced, with the CDP achieving its best result in party history, and the ruling LDP coalition being limited to a minority.

Noda was born in Funabashi on 20 May 1957, the son of a paratrooper in the Japan Self-Defense Forces. Unlike many prominent Japanese politicians, Noda has no family connections to Nagatachō. His parents were too poor to pay for a wedding reception.

Noda graduated from Chiba Prefectural Funabashi Senior High School in 1975. He graduated from Waseda University with the B.A. degree in Political Science in 1980 and was later accepted into the Matsushita Institute. This institution was founded by Kōnosuke Matsushita (the founder of Panasonic) to groom future civic leaders of Japan. While attending the Matsushita Institute, Noda read household gas meters as a part-time job in his native Chiba Prefecture, partially in order to get to know his future constituents better in preparation for a run for office. He was first elected to the assembly of Chiba Prefecture in 1987 at the age of 29.

In 1993, he was elected to the Diet for first time, as one of four members of Chiba 1st district as a member of the now-defunct Japan New Party. After the multi-member districts were abolished in the 1994 Japanese electoral reform, Noda stood in Chiba 4th district in the 1996 election, but was defeated. He later joined the Democratic Party of Japan (DPJ) and successfully contested Chiba 4th in the 2000 election. As a member of the DPJ, he served as its Diet affairs chief as well as head of the party's public relations office.

In October 2005, Noda criticized Prime Minister Jun'ichirō Koizumi for his position on Japanese class A war criminals as "war criminals". However, Noda supported Koizumi's visit to Yasukuni Shrine.
