Derby's 20-year-old goalkeeper Lee Grant produced a fantastic display to frustrate Millwall at The Den.
The Lions were by far the better side but failed to break the deadlock in a tame stalemate on a rain-soaked afternoon.
Manager Dennis Wise paid tribute to Grant and said he was delighted with his team's effort.
He said: "I can't ask for anything else from my lads. Derby never had a shot and we deserved to win but their keeper was magnificent. Today hit me in the face. We need to get some strikers." Rams boss Craig Burley was pleased to escape with a point and heaped praise on Grant.
He said: "At the start of the season he made a few errors but since he's come back he's been outstanding.
"We did not play well in possession but got another clean sheet and a point." This game had 0-0 written all over it from the start. The omens were bad when Bob Peeters, Millwall's only recognisable striker, trudged off injured after only seven minutes.
That left the Lions with two midfielders, Paul Ifill and Tim Cahill, up front.
It took the Rams 68 minutes to win their first corner and they failed to muster a single shot in the entire 90 minutes.
Millwall worked hard and caused problems for the Derby defence. On 43 minutes Cahill hit the bar from two yards after Youl Mawene headed David Livermore's seven-yard shot off the line, but it was a rare moment of excitement.
Grant produced a brilliant fingertip save from a Cahill header in the second half and parried several long-range efforts from Ifill.
There were strong performances from Millwall widemen Peter Sweeney and substitute Aboubaka Fofana but the hosts could not break the deadlock and were left frustrated at the final whistle.
