樹螺科（學名：Helicinidae），又名䗉螺科[2][3]、䗉蝸牛科[4][5]或無臍蝸牛科[6]，是軟體動物門腹足綱之下的一個科，舊屬蜑螺總科（Neritacea），今獨立出來成為樹螺總科之下唯一的一個科。本科的物種在其殼口均有厴可封蓋其殼。皆為陸生。
雖然本科物種在外表跟陸地上呼吸空氣的蝸牛很相似，但其實在分類學來說，兩者的分歧頗大。
本科物種的分佈比較奇怪：牠們生活於熱帶及亞熱帶地區，但只限於加勒比海的島嶼及部份印度太平洋區及太平洋的島嶼，也在亞洲及澳大利亞大陸的邊緣地區生活。
根據2005年《布歇特和洛克羅伊的腹足類分類》的分類，本科由蜑螺總科之下轉為成立獨立的一個總科[7]。本科由六個亞科組成，分別如下：
- 樹螺亞科 Helicininae Férussac, 1822：即 Olygyridae Gray, 1847 或 Bourcierinae Paetel, 1890
- Ceratodiscinae Pilsbry, 1927
- † Dimorphoptychiinae Wenz, 1938[8]
- Hendersoniinae H. B. Baker, 1926
- Stoastomatinae C. B. Adams, 1849
- Vianinae H. B. Baker, 1922
截至2020年2月9日 (2020-02-09)[update]，MolluscaBase紀錄樹螺亞科（Helicininae）包括下列22個屬[9]：
