Ipswich stretched their unbeaten run to four matches and hit the 50-point mark while FA Cup semi-finalists Millwall remain a point better off.
Andy Keogh had a goal disallowed and clipped the woodwork for the hosts while David Forde denied Luke Hyam in the first half.
After the break, Lions defender Shane Lowry hit a post and Michael Chopra and Frank Nouble squandered the best of Ipswich's few opportunities.
