Nuttall suggested a new limit of 12 weeks in contrast to the current 24 week limit.
Speaking on LBC Radio he said scientific and medical advances meant children could survive if born before the current limit.
He said: "I've been pretty open about my views on abortion for many, many years.
"I would like to see the limit for abortion reduced simply because we've had scientific and medical advances."
Asked by host Nick Ferrari to what level he would want the limit cut he replied: "12 weeks, which is the same as the Health Secretary Jeremy Hunt and I believe the same as Tim Farron, the leader of the Liberal Democrats."
In the past Nuttall said there would be a referendum on changing abortion laws if "enough people required it", if UKIP was in power.
