Online donors have reached into their pockets to help raise more than $250,000 for victims of the East Village explosion.

Several pages have been set up on GoFundMe.com to help the dozens of people who lived in the three Second Avenue buildings that collapsed following the massive March 26 blast, which killed two.

Nearly 40 percent of the crowd-fund money was donated to Diane McLean, a single mother of three who lived at 45 E. 7th Street for more than 30 years.

The 58-year-old child psychiatrist’s page was set up by her kids’ baby sitter, and has amassed $96,630 in just two weeks.

“Here’s what’s so moving,” she told The Post, fighting back tears. “People all over are anonymously giving us money. I’m just so humble and so grateful.”

McLean lived in one of the three rent-stabilized apartments at No. 45, the residential side of 119 Second Ave., paying $1,500 for a three-bedroom apartment.

Meanwhile, punk rocker Patti Smith headlined a sold-out benefit concert at Theater 80 Sunday night that helped raise $50,000.

“It’s painful enough to lose so much history,” Smith told The Post, “not to mention everything these people lost in all this mishap of greed.”

Authorities believe an illegally tapped gas line sparked the blast.
