Counter-terror officers preparing a raid on a house in the Trumanlaan district have surrounded a building a few hundred yards from 24 Oktoberplein where the shooting took place.
All mosques in Utrecht have been evacuated and the Utrecht University and Utrecht Central train station are also on lockdown, according to NOS.
Three trauma helicopters were called to the scene and police have appealed for the public to keep the roads clear for emergency services.
A witness, Jimmy de Koster, told RTV Utrecht he saw a woman lying on the ground shouting: "I didn't do anything."
Four men rushed towards her in an attempt to drag her to safety, but a gunman opened fire again, forcing them to take cover, he said.
It was not immediately clear if it was a lone attacker or if it was a coordinated attack involving more than one gunman. Local news outlet AD said police were looking into other reported shootings at nearby locations and whether or not they are linked.
Dutch Prime Minister Mark Rutte said the Government and the country's anti-terrorism coordinator were holding a "crisis meeting" in the aftermath of the shooting.
He said the situation was "very worrying", and security was tightened at The Hague. Schools in the area have been told to keep their doors closed.
Mayor of Utrecht Jan van Zanen said: "Shortly before noon a shooting took place on a tram in Utrecht around 24 Octoberplein. A horrible and radical incident in which victims have fallen. My thoughts are with them and their loved ones.
"I am in close contact with the police and the public prosecutor... I can confirm that the police and the public prosecutor are currently looking for the person responsible for this incident.
"The most important thing at the moment is taking care of the wounded and investigating the circumstances of the incident. We do not exclude anything, not even a terrorist attack."
