3511 (three thousand, five hundred and eleven) is the natural number following 3510 and preceding 3512.

3511 is a prime number, and is also an emirp: a different prime when its digits are reversed.[1]

3511 is a Wieferich prime,[2] found to be so by N. G. W. H. Beeger in 1922[3] and the largest known[4] – the only other being 1093.[5] If any other Wieferich primes exist, they must be greater than 6.7×1015.[4]

3511 is the 27th centered decagonal number.[6]
