Kruppel樣因子4（英語：Kruppel-like factor 4，縮寫KLF4）或腸富集Krüppel樣因子（英語：gut-enriched Krüppel-like factor，縮寫GKLF）是鋅指轉錄因子KLF家族的一個成員，後者屬於一個較大的SP1（英語：Sp1 transcription factor）樣轉錄因子家族^[5]^[6]^[7]。KLF4參與細胞增殖、細胞分化、細胞凋亡和體細胞重編程（英語：Reprogramming）的調節。有證據表明KLF4在包括大腸癌在內的一些癌症中是腫瘤抑制基因^[8]。與KLF2（英語：KLF2）類似，它在C端有三個C2H2型鋅指^[6]。它有兩個核定位序列指引它定位於細胞核內^[9]。在胚胎幹細胞(ESCs)和間充質幹細胞(MSCs)中KLF4是顯示多能化的很好標記。
