節蛙科（學名：Arthroleptidae）是兩棲綱無尾目的一科。該科包括8屬200余種，體型小，體長不超過4厘米。它們主要棲息在林地地表的落葉層上，完全陸棲，因此沒有蝌蚪階段。它們會在地面、巖石裂縫或落葉中產卵，有些孵化出來直接是完成變態的小蛙，另一些則留有尾巴。
分布范圍
節蛙科的成員主要分布于撒哈拉沙漠以南的非洲地區，包括喀麥隆到剛果一帶的熱帶雨林中。
生活習性
科學家在研究節蛙科的過程中，發現了這一科類群中的一部分成員具有戲劇性的防御模式：在遇到危險時，它們會將骨頭折斷，之后鋒利的“爪”會刺透趾墊從斷裂處長出，還可使其更牢固的抓住巖石。然而，這種防御模式的進化原因尚未明確。
下級分類
節蛙科（Arthroleptidae）包括節蛙亞科（Arthroleptinae）和小黑蛙亞科（Leptopelinae），共8屬200余種，分布于撒哈拉沙漠以南的非洲。
小型的陸棲蛙，體長不到4厘米，主要棲息在林地地表的落葉層上。大多身體細長，有或無蹼。繁殖時腋部抱合，將卵產于水中，可孵化成自由游泳的蝌蚪。
節林蛙屬（Arthroleptis）等少數類群在陸地產卵，一次約10～30枚，卵直接孵出具尾或不具尾的幼蛙，以適應陸地生活。
發蛙（Trichobatrachus robustus）又稱壯發蛙、骨折蛙、多毛蛙、毛毛蛙，分布于非洲中部。發蛙還以能伸縮的“爪”而著名，不過這種爪并不是由角蛋白構成的真正的爪，而是骨骼。遇到危險時，發蛙會將骨頭折斷，之后鋒利的“爪”會刺透趾墊從斷裂處長出，還可使其更牢固的抓住巖石。
雄蛙的尾部有狹長的肺憩室，繁殖期的雄性發蛙還會在腹部和后肢兩側上長出毛發狀的真皮乳突，內含很多微小動脈，陸棲時可以增加表皮的吸氧量，其作用相當于水棲時的外鰓，也因此得名。
