Hazin Lahiji (Persian: حزین لاهیجی; 8 January 1692 – 15 October 1766), was an Iranian historian, theologian and philosopher.

Hazin belonged to a family of scholars and landowners in the northern Iranian province of Gilan,[1] which mainly resided in the town of Astara.

In order to complete his studies, Hazin's father Abu Talib Lahiji—a philosopher from Lahijan—relocated to Isfahan during the reign of Shah Solayman (r. 1666–1694).

Because intellectuals would assemble at his father's home, he got the chance to meet several of the poets and academics he mentions in his later book named Tazkirat al-Mu'asirin.

[5] Having eventually sold everything but his books, Hazin tried unsuccessfully to convince Shah Soltan Hoseyn (r. 1694–1722) and his own remaining family and friends to leave the famine-stricken city before it was too late.
