Mariano Mullerat i Soldevila (24 March 1897 - 13 August 1936) was a Spanish Roman Catholic doctor who also served as the mayor for Arbeca from 1924 until March 1930. Mullerat studied medicine in Reus and Barcelona before he married in 1922 and settled with his wife in Arbeca where he pursued his private medical practice. He was a staunch Catholic traditionalist who defended Catholic dogma from liberalist interpretations and as a doctor provided free care for the poor and would even help them with their material needs. In his tenure as mayor he helped organize religious solemnities and was also known to pursue those who made blasphemous claims and slander in public.
