Шаблон:Infobox number 143 (one hundred [and] forty-three) is the natural number following 142 and preceding 144.

In mathematics

143 is the sum of seven consecutive primes (11 + 13 + 17 + 19 + 23 + 29 + 31). But this number is never the sum of an integer and its base 10 digits, making it a self number. It is also the product of a twin prime pair (11 × 13).

Every positive integer is the sum of at most 143 seventh powers (see Waring's problem).

143 is the difference in the first exception to the pattern shown below:

<math>3^2+4^2=5^2</math>
<math>3^3+4^3+5^3=6^3</math>
<math>3^4+4^4+5^4+6^4=7^4-143</math>.
