Two goals in three minutes from Sam Nombe put Rotherham in front at the break but Bolton rallied to earn a point and extend their unbeaten streak to 12 games.
A 60-year wait for a win at Rotherham goes on as a late onslaught failed to find a winner.
Rotherham snuck ahead after 39 minutes when a Joe Powell cross fell kindly to Nombe who tucked the ball beyond Jack Bonham.
The same man struck again in the 42nd minute as he was found in space by Ar'Jany Martha and lashed low past Bonham.
Bolton got one back in the 51st minute with Chris Forino poking in from close-range following a corner.
The visitors pushed for a leveller with Johnny Kenny forcing Tedd Cann into a diving save after breaking from the halfway line.
The leveller came after 83 minutes with Sam Dalby nodding in from Kenny's cross to the near post.
