A suicide bomber detonated a lorry near the offices of a Kurdish political party, the Patriotic Union of Kurdistan (PUK), causing most of the casualties.
Another bomb went off at a bus station. No group has claimed either attack.
The status of Kerkuk is disputed by Turkmen Iraqis, Kurds and Arabs. The number of bombings in the region has been increasing in recent months.
Witnesses to the attack on the offices of the PUK - a party led by Iraqi President Jalal Talabani - said the massive explosion there left a crater several metres deep.
More than 20 cars were destroyed, two buildings collapsed completely and a number of shops were also damaged.
Dozens of bodies are said to be buried in the rubble and the death toll is expected to rise.
"Most of the wounded, which include women and children, are in a critical condition," Kerkuk's police chief told AFP news agency.
In the second attack, about 15 minutes later, a bomber struck the bus station at the nearby market.
On 7 July a truck bomb killed 105 people at market in the Turkmen town of AMIRLI, south of Kerkuk.
