贵腐甜白酒（德语：Trockenbeerenauslese），又名贵腐酒，是一种甜葡萄酒，源自匈牙利，利用过份成熟而在树上干萎的葡萄酿制。特色是糖份比较高，味道甜美，被认为是顶级的甜白葡萄酒。一般而言随着时日增长，贵腐甜酒会由金黄色，变成琥珀色或橘红色。

葡萄在过份成熟时有机会感染真菌Botrytis cinerea（俗称贵腐霉 Noble rot），令果皮出现孔洞，水份挥发，呈现类似葡萄干的状态。这时的葡萄糖分和其他成分相对一般浓缩，甜度达每公升340克的糖分。 经过酿酒过程，部份糖份被酵母转化成酒精。当酒精浓度达16%，酵母菌便会死去令到发酵作用停止。酒液中余下的糖份便造成了这白酒的独殊风味。

Trockenbeerenauslese (literal meaning: "dried berries selection") is a German language wine term for a medium to full body dessert wine.

Trockenbeerenauslese is the highest in sugar content in the Prädikatswein category of the Austrian and German wine classifications. Trockenbeerenauslese wines, often called "TBA" for short, are made from individually selected grapes affected by noble rot, i.e. "botrytized" grapes.
