The theme for this year's festival is Agriculture and Farm Egging: Past, Present and Future.
It's a way to honor the impact the egg industry had in the past and how the region is rich in farming now.
Organizers say the festival is a huge economic event for Pittsfield and the surrounding area.
"Thousands of people come in and they buy items from the gas stations, to all of the restaurants, to the stores," said Pittsfield Town Manager Kathryn Ruth. "A lot of money is spent here during that week."
The Egg Festival runs Monday, July 8 through Saturday, July 15, with events like the Little Chick Contest and "Egglympics."
It will certainly be a summer full of celebrations in Pittsfield, as the town is set to celebrate its 200th anniversary in June.
