In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event.

Rozkład Poissona (czytaj [p w a s ɔ̃], także prawo Poissona małych liczb [1]) – dyskretny rozkład prawdopodobieństwa, wyrażający prawdopodobieństwo szeregu wydarzeń mających miejsce w określonym czasie, gdy te wydarzenia występują ze znaną średnią częstotliwością i w sposób niezależny od czasu jaki upłynął od ostatniego zajścia takiego zdarzenia.
