Globally, ធីរិទ្ធ (ធីរិទ្ធ 
, Thirith 
) is a rare largely boy's, but uncommonly female first name. The forename ធីរិទ្ធ is characteristic of Cambodia, where it is quite a rare predominantly male, but very seldom female name, and India, where it is an extremely rare largely boy's, but uncommonly feminine name. Much less frequently, ធីរិទ្ធ is the last name as well as the forename.
