Vector　particles＇　Hawking　radiation　as　tunneling　from　the　apparent　horizon　of　Vaidya　black　holes　is　investigated.　By　applying　the　WKB　approximation　and　the　appropriate　ansatz　for　the　form　of　the　action　to　the　Proca　equation,　we　obtain　the　tunneling　spectrum　of　vector　particles.　As　a　result,　the　expected　Hawking　temperature　is　recovered　by　vector　particles　tunneling　from　the　apparent　horizon　of　Vaidya　black　holes.
