堤喀（希腊语：Τύχη）也称堤刻，梯刻，泰姬或太姬，是希腊神话中的机缘女神，相当于罗马神话的福尔图娜。一般被认为是提坦神俄刻阿诺斯和忒堤斯的女儿，有时也认为是宙斯的女儿。她常常以一位头戴壁形金冠的少女形象出现。常与涅墨西斯和阿格忒斯·岱蒙一起行动。

Tyche (English /ˈtaɪki/; from Greek:Τύχη, meaning "luck"; Roman equivalent: Fortuna) was the presiding tutelary deity that governed the fortune and prosperity of a city, its destiny. She is the daughter of Aphrodite and Zeus or Hermes.

In literature, she might be given various genealogies, as a daughter of Hermes and Aphrodite, or considered as one of the Oceanids, daughters of Oceanus and Tethys, or of Zeus. She was connected with Nemesis and Agathos Daimon ("good spirit").
