The Miss Ilocos Sur pageant is an annual provincial pageant held in the province of Ilocos Sur, commonly every February within the Kannawidan or Ilocos Sur Festival, celebrating the founding anniversary of Ilocos Sur.
The pageant is once known as the Saniata ti Ylocos Sur competition until its name was changed into Miss Ilocos Sur starting 2023. It was made part of the newly introduced Kannawidan Festival by the then late Governor DV Savellano. Its winners represent the province in national competitions, such as Binibining Pilipinas and Mutya ng Pilipinas. The first edition was held in 2008, where Patricia Francisco won, becoming the inaugural titleholder.
Along with the Miss Ilocos Norte, Mutia ti La Union and Limgas na Pangasinan pageants, these pageants are the big four local pageants of the Ilocos Region.
The Saniata's court consists of the winner, the Saniata ti Ylocos, it's runner ups, the Saniata World, Saniata Tourism, Saniata Environment, the 1st and 2nd runner ups.
