A Brooklyn lawyer who turned out to be Manhattan’s notorious serial “Gentleman Groper” got a wrist-slap, no-jail sentence yesterday that may let him even keep his law license.

Paul Kraft, 31, had pleaded guilty in March to a string of five between-the-leg gropings of random pedestrian women on the Upper East Side and lower Manhattan last year.

A wrong man was initially collared last year, before Kraft was busted in December and admitted to the attacks.

Prosecutors had cited Kraft’s lack of criminal history and that he had taken responsibility for his actions in agreeing to the plea deal, which dismissed the top count of unlawful surveillance — for his allegedly putting his cellphone under the skirt of one woman.

Under the sentence, Kraft will go once a week for 18 months to the Brooklyn-based “Mustard Seed” program, a sexual-impulse-therapy program.
