There is no more "open fire" but some grass and brush is still smoldering, said the State Emergency Service of Ukraine.
Three aircraft, three helicopters and more than 400 firefighters were used to control the blaze, which raged for several days.
Forest fires are not uncommon in the deserted 1,000-square-mile exclusion zone, which was evacuated following the devastating 1986 blast at the nuclear power plant that sent radioactive fallout billowing across Europe, exposing millions to dangerous levels of radiation.
Fears had been raised that the fires could overrun the nuclear power plant and a radioactive waste storage facility.
Emergency services said Tuesday radiation levels in Kiev and the surrounding region are "within normal limits."
On Monday Chernobyl tour operator Yaroslav Yemelianenko reported fires were burning within two kilometers (1.2 miles) of the nuclear reactors and the storage facility in a video posted on Facebook.
"The situation is critical. The exclusion zone is blazing. Local authorities report that everything is under control, but in fact, fire is rapidly spreading to new territories," he wrote in the post.
