Text of the Seventeenth Amendment to the United States Constitution
{{blockquote|The Senate of the United States shall be composed of two Senators from each State, elected by the people thereof, for six years; and each Senator shall have one vote. The electors in each State shall have the qualifications requisite for electors of the most numerous branch of the State legislatures.
When vacancies happen in the representation of any State in the Senate, the executive authority of such State shall issue writs of election to fill such vacancies: Provided, That the legislature of any State may empower the executive thereof to make temporary appointments until the people fill the vacancies by election as the legislature may direct.
This amendment shall not be so construed as to affect the election or term of any Senator chosen before it becomes valid as part of the Constitution.}}

Appointments of senators-elect to the Senate
{{For|a list of senators-elect appointed to the Senate after being elected|#List of senators-elect appointed to the Senate}}
In the past, retiring or defeated senators often resigned after the general election but before the expiration of their term due to various reasons.
One of the common reason was to allow state governors to appoint their successors to the vacated seat. This enabled their successors to gain extra seniority over other freshmen senators for the purposes of obtaining choice committee assignments. This practice ended in 1980 after both parties established new party rules that no longer gave seniority to senators who entered Congress early by being appointed to fill the vacancy just before the end of a Congress. Seniority still counted in obtaining choice of office and parking space assignments.{{cite web |last1=Mulkern |first1=Anne C. |title=Senators giving "out of office" goodbyes |url=https://www.denverpost.com/2008/11/24/senators-giving-out-of-office-goodbyes/ |website=The Denver Post |access-date=December 10, 2018 |date=November 24, 2008 |archive-url=https://web.archive.org/web/20181214164045/https://www.denverpost.com/2008/11/24/senators-giving-out-of-office-goodbyes/ |archive-date=December 14, 2018 |url-status = live}}{{cite web |title=GOP Seeks Fruits of Victory as 97th Convenes |url=https://library.cqpress.com/cqalmanac/document.php?id=cqal81-1170993 |website=CQ Almanac Online Edition |access-date=December 10, 2018}}
In the election years of 1966, 1974, and 1978, changes to pension laws made it advantageous for senators to resign before December 31, rather than wait until their term expired in early January, contributing to the increase in the number of appointed senators.{{cite web |last1=Rakich |first1=Nathaniel |title=We've Never Seen Congressional Resignations Like This Before |url=https://fivethirtyeight.com/features/more-people-are-resigning-from-congress-than-at-any-time-in-recent-history/ |website=FiveThirtyEight |access-date=December 10, 2018 |date=January 29, 2018 |archive-url=https://web.archive.org/web/20181214164416/https://fivethirtyeight.com/features/more-people-are-resigning-from-congress-than-at-any-time-in-recent-history/ |archive-date=December 14, 2018 |url-status = live}}
In addition, 3 senators died after the election of their successors, allowing their successors to be appointed and take office early.{{cite web |title=U.S. Senate: Senators Who Have Died in Office |url=https://www.senate.gov/senators/SenatorsDiedinOffice.htm |website=United States Senate |access-date=December 10, 2018 |archive-url=https://web.archive.org/web/20181223141527/https://www.senate.gov/senators/SenatorsDiedinOffice.htm |archive-date=December 23, 2018 |url-status = live}}
