Catalan numbers form a sequence of natural numbers that counts a plethora of objects in mathematics. Thus, they appear constantly in enumerative combinatorics and many related fields like algebra, discrete geometry, representation theory and more. I will present their origin, discuss about some recursive and closed formulas and finally show some objects that are counted by Catalan numbers.
