This is a list of prime ministers of the United Kingdom by age. This table can be sorted to display prime ministers of the United Kingdom by name, order of office, date of birth, age at appointment, length of retirement, or lifespan. Age at appointment is determined by the day a prime minister assumed office for the first time. Length of retirement is determined from the day a prime minister leaves office for the final time until their death.
Two measures of longevity are given; this is to allow for the differing number of leap days occurring within the life of each prime minister. The first figure is the number of days between date of birth and date of death, allowing for leap days; in parentheses the same period given in years and days, with the number of whole years that the prime minister had lived, and the days being the remaining number of days from their last birthday. Where the prime minister in question is still living, their longevity is measured up to 31 May 2024.

This is a graphical lifespan timeline of the prime ministers of the United Kingdom and they are listed in order of office.
The following chart shows prime ministers by their age (living prime ministers in green), with the years of their premiership in blue.
Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth. This can be defined in two ways. Cohort LEB is the mean length of life of a birth cohort and can be computed only for cohorts born so long ago that all their members have died. Period LEB is the mean length of life of a hypothetical cohort assumed to be exposed, from birth through death, to the mortality rates observed at a given year. National LEB figures reported by national agencies and international organizations for human populations are estimates of period LEB.
The prime minister of the United Kingdom is the head of government of the United Kingdom. The prime minister advises the sovereign on the exercise of much of the royal prerogative, chairs the Cabinet and selects its ministers. As modern prime ministers hold office by virtue of their ability to command the confidence of the House of Commons, they sit as members of Parliament. The current prime minister is Rishi Sunak of the Conservative Party, who assumed the office on 25 October 2022.
Longevity may refer to especially long-lived members of a population, whereas life expectancy is defined statistically as the average number of years remaining at a given age. For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year.
The prime minister of Belgium or the premier of Belgium is the head of the federal government of Belgium, and the most powerful person in Belgian politics.
Maximum life span is a measure of the maximum amount of time one or more members of a population have been observed to survive between birth and death. The term can also denote an estimate of the maximum amount of time that a member of a given species could survive between birth and death, provided circumstances that are optimal to that member's longevity.
A supercentenarian, sometimes hyphenated as super-centenarian, is a person who is 110 years or older. This age is achieved by about one in 1,000 centenarians. Supercentenarians typically live a life free of significant age-related diseases until shortly before the maximum human lifespan is reached.
The chief justice of Canada is the presiding judge of the nine-member Supreme Court of Canada, the highest judicial body in Canada. As such, the chief justice is the highest-ranking judge of the Canadian court system. The Supreme Court Act makes the chief justice, a Crown in Council appointment, meaning the Crown acting on the advice of the prime minister and minister of justice. The chief justice serves until they resign, turn 75 years old, die, or are removed from office for cause. By tradition, a new chief justice is chosen from among the court's incumbent puisne justices.

This is a list of tables of the oldest people in the world in ordinal ranks. To avoid including false or unconfirmed claims of old age, names here are restricted to those people whose ages have been validated by an international body dealing in longevity research, such as the Gerontology Research Group or Guinness World Records, and others who have otherwise been reliably sourced.
United States senators are conventionally ranked by the length of their tenure in the Senate. The senator in each U.S. state with the longer time in office is known as the senior senator; the other is the junior senator. This convention has no official standing, though seniority confers several benefits, including preference in the choice of committee assignments and physical offices. When senators have been in office for the same length of time, a number of tiebreakers, including previous offices held, are used to determine seniority. Per traditions, the longest serving senator of the majority party is named president pro tempore of the Senate, the second-highest office in the Senate and the third in the line of succession to the presidency of the United States.
Heads of state throughout the world and at all periods of history may be ranked according to characteristics such as length of time holding that position; age of accession or death; or physical attributes. World records in these characteristics may be identified, though the historical basis for such claims is frequently uncertain.
Deaths of United States federal judges in active service have profound political and procedural effects. Due to their implications for the political composition of the courts on which they serve, they can result in unexpected political conflicts regarding appointments to fill those seats. Such incidences can also disrupt the operations of the court with respect to active cases assigned to the deceased judge, and with opinions written by the deceased judge but not yet distributed. Historically, the rate of judges dying in active service was highest in the early days of the country, but declined sharply as lifespans increased, and as various legislation was introduced first allowing retiring judges to collect a pension, and later allowing judges to transition from active service to senior status, continuing to do judicial work in a semi-retired state.
