Papyrus 20 (in the Gregory-Aland numbering), designated by 𝔓20, is an early copy of the New Testament in Greek.

The text is neatly written in upright semi-cursive letters.

[2] The Greek text of this codex is representative of the Alexandrian text-type (rather proto-Alexandrian).

[1] This manuscript shows the greatest agreement with Codex Sinaiticus and Vaticanus,[3] but not with codices Ephraemi, Regius and other late Alexandrian manuscripts.

[2] Philip Comfort has conjectured that the scribe who wrote 𝔓20 was also the same scribe who wrote 𝔓27, where the Greek letters α, β, δ, ε, λ, ι, μ, ν, ο, π, ρ, σ, ψ, υ, φ, ω are formed identically in both manuscripts.
