Helms Bakery was an industrial bakery on the border of Los Angeles and Culver City, in Southern California, that operated from 1931 to 1969. Currently the buildings have been adapted for use as retail shops, restaurants, and furniture showrooms; the complex is part of what is now called the Helms Bakery District.

In 1926, Paul Helms of New York took early retirement for health reasons and moved his family to Southern California. Helms started construction on a building between Washington and Venice Boulevards in 1930 and, on March 2, 1931, the Helms Bakery opened with 32 employees and 11 delivery coaches (trucks).

By the next year, the Helms Bakery had become the "official baker" of the 1932 Summer Olympics when Paul Helms won a contract to supply bread for the 1932 games in Los Angeles. His slogan was "Olympic Games Bakers - Choice of Olympic Champions."  Four years later, in time for the 1936 Summer Olympics, Germany asked Helms for his bread recipes. The U.S. teams at London and Helsinki requested his bread be served. Early Helms vehicles sported the Olympic symbol, and it also appeared on and was mentioned in, the Helms logo on the bread wrappers, the company logo, and sign.

The Helms motto was "Daily at Your Door" and every weekday morning, from both the Culver City facility and a second Helms Bakery site in Montebello, dozens of Helms coaches,] painted in a two-tone scheme, would leave the bakery for various parts of the Los Angeles Basin to San Gabriel Valley, when the network of freeways had not yet been built. One of each of these coaches is on display at the Petersen Automotive Museum in Los Angeles, the Lyon Air Museum in Santa Ana, and the LeMay Car Museum in Tacoma, Washington. In an apparent tribute to the Helms Bakery, a churro cart ("Willie's Churros") in Disney California Adventure is styled and painted to resemble a Helms delivery truck.

Each coach would travel through its assigned neighborhoods, with the driver periodically pulling (twice) on a large handle that sounded a whistle or stopping at a house where a Helms sign, a blue placard with an "H" on it, was displayed in their windows.]

The Helms company ceased operations in 1969.

The Marks family purchased Helms Bakery in the early 1970s and adaptive reuse of a historic structure. Covering the 11 acres, the improvements include restoring original neon signs on the roofs, creating two murals, restoring the Zigzag Moderne detailing. To honor the history of the bakery, a small museum was installed inside one of the retail stores.
