The notions of interval valued pentapartitioned neutrosophic sets (𝐼𝑉𝑃𝑁𝑆s), where the membership values of truth, contradiction, ignorance, unknown, and falsity always fall inside a closed interval [0,1] are introduced in this paper. Also an example of COVID-19 has been discussed using 𝐼𝑉𝑃𝑁𝑆. Later we have established some basic operations between 𝐼𝑉𝑃𝑁𝑆𝑠 and useful features of 𝐼𝑉𝑃𝑁𝑆s have also been presented and discussed.
