Neopentila acetato aŭ C₇H₁₄O₂ estas kemia kombinaĵo, apartenanta al la funkcia grupo de la esteroj de la acetata acido kaj neopentila alkoholo. Neopentila acetato estas senkolora likvaĵo, uzata kiel gustigagento kaj odorigagento en la nutrondustrio kaj en la fabrikado de kosmetikaĵoj kaj farmaciaĵoj. Kutime ĝi estiĝas per kondensiĝa reakcio aŭ per esterigo de Fischer-Speyer kun sulfata acido kiel katalizilo. Neopentila acetato estas malmulte solvebla en akvo, sed tute solvebla en alkoholo, duetila etero, kloroformo kaj plejmulto el la organikaj solvantoj. Neopentila acetato reakcias kun fortaj oksidigagentoj kaj fortaj bazoj kaj posedas antifungajn kaj antibakteriajn proprecojn.
