59 is the smallest number which when divided by 2, 3, 4, 5, and 6, leaves remainders of 1, 2, 3, 4, and 5, respectively. [Astle]
59 is the smallest odd prime p such that prime(p) divides 2*3*5*7*11*...*p + 1. [McAlee]
59 inches equals 1 yard, 1 foot, and 11 inches. [McAlee]

The number of times the minute and second hands on a clock are aligned in one hour. [Fellows]
(5959 + 259)/(59 + 2) is prime. [Poo Sung]
59 = 5*9 + (5*9). It is probably the only multidigit number with this property. [Firoozbakht]
e^(*sqrt(59)) is a near-integer. Note that it is approximately one tenth of the total number of stars in our galaxy. [Jevtic]
Choose two 2-digit numbers of the form n and n+4 from different decades (for our purpose two 2-digit numbers are from different decades if their leftmost digits are not equal). Now reverse the digits of these two numbers and subtract the smaller from the larger. The result is always 59. Examples: 29 and 33 becomes 92 - 33 = 59, 57 and 61 becomes 75 - 16 = 59. [Green]
The smallest prime p such that (p, p + 2) and ((p), (p) + 2) both form twin prime pairs. [Beedassy]
"The Black '59" is a short story written by Bill Mumy (known primarily as Will Robinson in the 1960's CBS sci-fi television series Lost in Space).
59 is the smallest prime you can express by using the digits 123456789 in order, and the operators + and * between any digits. For example, 1*2*3*4+5+6+7+8+9 = 59. Can you find another way to express it with the same rules? [Ward]

2^59*(59!)-1 is the largest "almost evenian prime" less than a googol. ("An almost evenian number" is a number that can be represented as the product of first n positive even numbers minus 1 and is given by the form 2^n*n!-1, where n is the number of even numbers), (see PC97). [Loungrides]
