The Department of Marine Resources said the harvest of Maine's signature seafood broke the previous weight record of 81.2 million pounds, set in 2009.
The catch was the third most valuable on record. The top year was 2005, when the harvest was worth $317.9 to lobstermen.
Lobstermen averaged $3.31 a pound for their catch, representing a 14 percent increase from a year earlier.
Officials said the overall seafood harvest in Maine last year totaled 245.3 million pounds valued at $448.7 million. The catch was up 14 million pounds from 2009, while the value of the catch increased about $120 million.
