text: There are indeed Cambodian Catholics.  The website for the Catholic Church in Cambodia can be found in the resources section below.  Catholicism was brought to Cambodia in 1555 by Fr. Gaspar Da Cruz, a Portuguese Dominican.  The history page on the Catholic Church in Cambodia tells the interesting story of the arrival of Catholicism to Cambodia.  See the link below.  I've also included below a link regarding certain Catholic missions to Cambodia.  \nI hope this helps!
