唐納德·約翰·特朗普（英語：Donald John Trump^{[註 4]}，1946年6月14日－），美國共和黨籍政治人物，第45任美國總統。在踏入政前，川普也是企業、電視節目主持人、電影演員。

唐納·川普出生成長於紐約州紐約市皇后區，為特朗普集團前任董事長兼總裁及特朗普娛樂公司的創辦人，在全世界經營房地産、賭場和酒店^{[註 5]}。1996年至2015年間，特朗普旗下擁有美國小姐和環球小姐選美比賽，還在2004年至2015年間主持NBC的一檔電視真人秀列節目《誰是接班人》。2017年時，《福斯》將他列為世界上第544名最富有的人（美國第201名），截至2020年有着22億美元的淨資産。

川普在1987年時第一次公開達對競選公職的興趣。他在2000年贏得加州和密歇根州的改革總統初選，但在早期就退出競選。2015年6月，他開始自己的2016年總統選舉活動，他的競選活動獲得前所未有的媒報道和國際關註。

他在2016年11月8日贏得過半選舉人票而當選總統，並擊敗民主對手希拉蕊·林頓。部分評論將他的政治立場描述為民粹主義、保護主義和民族主義。他是美國歷史上最富有以及第一個先前沒有擔任過任何軍職或公職的總統，也是胜任者獲得較少普選票而當選的美國總統的人。也因爲他的許多爭議言論和行動，激起反川普抗議活動。

根據羅伯特·穆勒領導的特律師調查，特朗普和他的競選活動或從俄羅斯疑似預2016年總統大選中受益，但沒有找到足夠的證來指控共謀犯罪或與俄羅斯協調。穆勒同時調查特朗普妨礙司法公正，他的報告既沒有起訴特朗普，也沒有為他開脫罪責。在特朗普請求烏蘭政府調查前副總統拜登，衆議院於2019年12月以濫用職權和藐視國會為由對他進行第一次彈劾。參議院於2020年2月宣佈他兩項指控無罪。

在美國東部時間2021年1月13日，特朗普因被國會民主人指控煽動2021年衝擊美國國會大廈事件為由而受第二次彈劾。彈劾議案以232-197的比例通過衆議院，特朗普成為美國史上唯一一位受二次提案彈劾的總統。

Donald John Trump (born June 14, 1946) is an American politician who was the 45th president of the United States from 2017 to 2021. Before entering politics, he was a businessman and television personality.

Born and raised in Queens, New York City, Trump attended Fordham University for two years and received a bachelor's degree in economics from the Wharton School of the University of Pennsylvania. He became the president of his father Fred Trump's real estate business in 1971, which he renamed The Trump Organization; he expanded the company's operations to building and renovating skyscrapers, hotels, casinos, and golf courses. Trump later started various side ventures, mostly by licensing his name. Trump and his businesses have been involved in more than 4,000 state and federal legal actions, including six bankruptcies. He owned the Miss Universe brand of beauty pageants from 1996 to 2015, and produced and hosted the reality television series The Apprentice from 2004 to 2015.

Trump's political positions have been described as populist, protectionist, isolationist and nationalist. He entered the 2016 presidential race as a Republican and was elected in an upset victory over Democratic nominee Hillary Clinton while losing the popular vote.^[a] He became the first U.S. president without prior military or government service. His election and policies have sparked numerous protests. Trump made many false and misleading statements during his campaigns and presidency, to a degree unprecedented in American politics. Many of his comments and actions have been characterized as racially charged or racist.

During his presidency, Trump ordered a travel ban on citizens from several Muslim-majority countries, citing security concerns; after legal challenges, the Supreme Court upheld the policy's third revision. He enacted a tax-cut package for individuals and businesses, rescinding the individual health insurance mandate penalty of the Affordable Care Act (ACA). He appointed Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett to the Supreme Court. He reacted slowly to the COVID-19 pandemic, downplayed the threat, ignored or contradicted many recommendations from health officials, promoted false information about unproven treatments and the availability of testing and fumbled vaccine distribution. In foreign policy, Trump pursued an America First agenda: he renegotiated the North American Free Trade Agreement (NAFTA) as the United States–Mexico–Canada Agreement (USMCA) and withdrew the U.S. from the Trans-Pacific Partnership trade negotiations, the Paris Agreement on climate change and the Iran nuclear deal. He imposed import tariffs which triggered a trade war with China, moved the U.S. embassy in Israel to Jerusalem and withdrew U.S. troops from northern Syria. He met three times with North Korean leader Kim Jong-un, but negotiations on denuclearization eventually broke down.

A special counsel investigation led by Robert Mueller found that Trump and his campaign benefited from Russian interference in the 2016 presidential election, but did not find sufficient evidence to press charges of criminal conspiracy or coordination with Russia.^[b] Mueller also investigated Trump for obstruction of justice and his report neither indicted nor exonerated Trump on that offense. Trump later pardoned five people who were convicted as a result of the Russia investigation. After Trump solicited Ukraine to investigate his political rival Joe Biden, the House of Representatives impeached him in December 2019 for abuse of power and obstruction of Congress. The Senate, after refusing to hear witness testimony, acquitted him of both charges in February 2020.

Trump lost the 2020 presidential election to Biden but refused to concede defeat. He attempted to overturn the results by making false claims of electoral fraud, pressuring government officials, mounting dozens of unsuccessful legal challenges and obstructing the presidential transition. Hours before the ceremonial counting of the electoral votes on January 6, 2021, Trump rallied his supporters and exhorted them to march to the Capitol, which they then stormed. Five deaths resulted,^[c] and Congress was evacuated. Seven days later, the House of Representatives impeached him again, for "incitement of insurrection", making him the only American federal officeholder to be impeached twice.
