59 divides 616161... 61 (repeated 29*n times, n integer), but 61 divides 595959... 59 (repeated 30*n times, n integer). Note that 29 and 30 are consecutive numbers and also that 59 and 61 are consecutive primes. [Capelle]

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]
Minimal number of reciprocals of primes required for their sum to exceed 2. [Schiffman]

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]
Norman Manley, of California, holds the record for most hole in ones with 59. [Camper]
The sum of the first 59 Cyclops primes is divisible by 59. Note that 588407/59 is also prime. [Gaydos]
For consecutive primes 29 and 31, 29*31 (mod 29+31) = 59 and 31*37 (mod 31+37) = 59, which is the first time the remainder appears consecutively. Can it appear more than twice for three other consecutive primes? [Bergot]
2^59 (576460752303423488) is the smallest power of two with no unique digits. Each of its digits appears at least twice. [Gaydos]
