Ihor Serhiiovych Trunov (Ukrainian: Ігор Сергійович Трунов; born 10 May 1992) is a Ukrainian sprint canoeist.

At the 2013 Summer Universiade he won silver in K-4 200 m. He is European Championships medalist.

At the 2017 European championships in Plovdiv, Bulgaria, he finished third in pair with Ivan Semykin in K-2 500 m.[3] But in November 2017, Trunov received a four-year suspension following a positive drug in-competition test taken in May 2017.

He was therefore stripped of the silver medal he won at the 2017 European championships.

[4] He returned to competitions after his ban ended and became 2021 World champion in the K–4 500 m event (together with Oleh Kukharyk, Dmytro Danylenko, and Ivan Semykin).
