'''非编码RNA'''(),缩写'''ncRNA''',是指各种不转译成[[蛋白质]]的[[RNA]][[分子]]。过去也称此类RNA为小RNA(sRNA)。不过有些ncRNA分子其实相当大。其他较少使用的同义词还有非[[信使RNA]](nmRNA)、小非信使RNA(snmRNA)或功能性RNA(fRNA)等。
[[DNA序列]]中专门[[转录]]成非编码RNA的部分称为'''RNA[[基因]]'''或是'''非编码RNA基因'''。非编码RNA基因用来生产tRNA([[转移RNA]])与rRNA([[核糖体RNA]]),以及一些小RNA,如snoRNAs、microRNAs、siRNAs与piRNAs;较大的则有Xist、Evf、Air、CTN与PINK等。
[[基因组]]中可生产非编码RNA的[[DNA]]比例目前仍未明了,最近的[[转录组]]及[[DNA微阵列|微阵列]]研究显示,在[[老鼠]]基因组中,可能有超过3万个长ncRNA。mRNA(信使RNA)末端也含有一些非编码区域(non-coding regions;UTRs),虽然这些部分并非蛋白质编码,但mRNA并不归类于非编码RNA。
