Alasiri (kutoka Kiarabu) ni kipindi cha mchana kati ya adhuhuri na jioni, wakati ukali wa mwanga wa jua unapozidi kupungua.

Pwani ya Atlantiki wakati wa alasiri.

Kwa kawaida wakati huo kwa binadamu unafuata mlo: hivyo utendaji wake unapungua pamoja na umakinifu wake. Ndiyo sababu ajali nyingi huwa zinatokea wakati huo.

Dini mbalimbali zenye ratiba ya sala, kwa mfano Ukristo na Uislamu, zina kipindi maalumu kwa alasiri.
