Petaluma's Butter & Egg Days Festivities Begin Saturday

PETALUMA, CA — Petaluma launches its annual Butter & Egg Days celebration this weekend, blending history, hometown pride, and a multi-week, downtown festival.

Organizers will open the festivities at noon Saturday at the Petaluma Historical Library and Museum, where city leaders will introduce the 2026 Good Egg and Grand Marshal.

Mayor Kevin McDonnell will deliver a formal proclamation recognizing the honorees and the community members they represent.

The opening precedes the main events beginning April 18, when Petaluma will send more than 100 parade units through its historic downtown.

Organizers expect roughly 3,000 participants and 200 volunteers to fill the streets as the parade steps off at noon. Clover Sonoma will lead the Clover Kids’ Parade at 11:30 a.m., featuring young children and families ahead of the main procession.

This year’s theme, “America’s Birthday – Petaluma Style,” invites participants to design floats and performances that celebrate the nation’s 250th anniversary while highlighting local agriculture, entrepreneurship, and creativity. Judges will award prizes based on how effectively entries bring the theme to life.

Festival organizers will expand the celebration across four downtown blocks from 10 a.m. to 5 p.m., offering food vendors, craft booths, and beverage gardens, including a Lagunitas-hosted space on B Street. Families can explore two dedicated children’s areas, including the Marin Health Kid Zone, while live music will anchor the Farmhouse Artisan Market stage.

New this year, organizers will introduce the Healthy Petaluma Community Relaxation Lounge at Blue Zones, providing a quiet, cooled space for attendees to recharge during the daylong event.

The celebration will continue the following weekend with the Annual Spring Antique Faire on April 26, extending the economic and cultural boost for downtown businesses.

Organizers say the event honors not only Petaluma’s dairy and egg farming legacy but also the broader community of farmers, immigrants, makers, and entrepreneurs who continue to shape the city’s identity.
