Fieldata er et tegnsæt, der kan benyttes af computere af fabrikatet UNIVAC af 1100-serien (i dag Unisys). Det er specielt ved kun at benytte 6 bit pr. tegn. UNIVAC kan også benytte ASCII uden problemer.
Fieldata var oprindeligt et fælles kampinformationssystem udviklet af US Army Signal Corps i slutningen af 1950'erne. I denne militære udgave af fieldata benyttes 7 bit til et tegn. Den syvende bit angiver små bogstaver (når den er 0) og store bogstaver (når den er 1). UNIVAC kunne kun benytte store bogstaver i fieldata og kunne nøjes med 6 bit.
UNIVAC 1100 havde en ordlængde på 36 bit, så der kan være 6 tegn i fieldata i ét ord. ASCII benytter (på UNIVAC) 9 bit, hvilket giver 4 tegn på den samme plads.
UNIVAC 1100-seriens direkte efterfølger, Unisys 2200-serien, kan også benytte fieldata.
