The two, soundman James Brolan, 42, and camera operator Paul Douglas, 48, died filming in Baghdad with a US army unit.
CBS correspondent Kimberly Dozier, who has dual British/US citizenship, was critically injured, while an American officer and Iraqi interpreter were also killed on a day of terrible bloodshed in Baghdad, which claimed the lives of 41.
The deaths of the two British journalists brings the total number of journalists killed in Iraq to 71.
Their deaths came as two British soldiers from the Queen's Dragoon Guards were killed in Basra when their Land Rover was targeted by insurgents, bringing the total number of British troops killed in Iraq to 113.
In a statement, Brolan's family said: "His unassuming nature and love of a practical joke often belied his well-read, 'university of life' intellect. He always took great pleasure on the road beating his Harvard, Yale or Oxbridge-educated correspondents at Scrabble and his knowledge of useless facts was unrivalled," they said.
Colleagues of Douglas said he was "one of those people you wanted around when the situation got tough".
Brolan was a former soldier in the Royal Green Jackets regiment and had become a soundman after leaving the Army. He had worked for CBS in Afghanistan and Iraq.
Douglas had worked for CBS for more than a decade and worked in many war zones, including Afghanistan and Bosnia.
