Ūsiņš () is a deity in Latvian mythology, the god of light and spring, symbol of fertility, guardian of horses and bees. It is one of few Latvian deities whose historical sources can be derived to be more or less genuine testimony. With Ūsiņš Day begins summer: as they bestow fields with green grass and trees with green leaves. Therefore on Ūsiņi guys drove horses to pieguļa for the first time. Ūsiņi coincidences with Jurģi on 23 April (in Gregorian calendar Ūsiņi falls on 9 May), which is the Christian Church's deposit. Ūsiņš has its own ornamental sign, which is similar to two letter E facing their backs against each other. This sign is the most common ornament for gloves. There is a belief, that such gloves grant the wearer with good luck on the road, and such gloves are called atslēgaiņi.

Auniņš called Ūsiņš the god of light, by explaining with the sound "us", which can also be found in the word aust ('day'). Also, in his study on Latvian deity Ūsiņš, Haralds Biezais concluded that Ūsiņš typologically belongs to the realm of heavenly deities, and the specific features allowed him to be considered as the god of light. If this interpretation is correct, he is therefore an astral deity connected to the morning and the evening star. On the other hand, Jānis Endzelīns felt that the word ūsiņš has no Latvian origin, but was borrowed from the Germanic word husing ('home spirit'). After some time, Endzelīns reflected on and considered that the word ūsiņš derives from a Russian word усень or овсень and that the same deity
