*Purpose: Delayed graft function (DGF) is one of the most common obstacles of donation after circulatory death (DCD) kidney transplantation. Serum free fatty acids (FFAs) has been proved to be related with inflammation and immunomodulation. But its role in kidney transplantation has not been fully studied.

*Methods: General data of recipients undergoing DCD kidney transplantation from July 25, 2017 to July 24, 2018 in our center were collected. FFAs pre-transplantation were analyzed.

*Results: There were 26 recipients developed DGF among 214 patients included. DGF patients experienced prolonged hospitalization and more complications (P < 0.050). Worse graft functions at hospital discharge and 1-year post-operation were noted in DGF group (P = 0.001). DGF group had higher levels of serum homocysteine (Hcy), FFAs, serum uric acid (UA) (P < 0.050). FFAs was a risk factor for onset of DGF (P < 0.001, value of area under ROC curve: 0.925 (0.856-0.994)), and serum creatinine (SCr) level at hospital discharge was a risk factor for poor outcomes of DGF patients (P = 0.040).

*Conclusions: DGF onset can be predicted by FFAs pre-transplantation. The internal mechanisms between FFAs and DGF need to be further explored by the next experimental studies.
