Novato Horsemen, has been a part of the Marin County community since 1939 and was incorporated in 1945. It co-sponsored Novato's original, "Western Weekend Parade & Rodeo", until 1978, which was the largest attended affair in Novato. The club is currently one of the largest horsemen associations in California but unfortunately, it is also one of the last remaining active horse clubs in a county which once hosted many barns and stables. As land values skyrocket, Novato Horsemen members strive to withstand "progress" to keep Novato and Marin County's horse heritage alive for future generations of children and adults.

The club, which consists of over 300 senior and junior members from the five surrounding Northern Bay Area counties, currently participates in a variety of cattle events, trail rides, and social affairs, as well as horsemanship education at the Horsemen's own facility. Horse owner or not, most activities are open to all within the community. Membership dues are kept low so anyone can participate. Members also donate their time to all activities, as well as maintaining the clubhouse facilities, arenas and grounds.

In addition to its own activities, Novato Horsemen support and participate in many other events including Novato's 4th of July Parade and the Grand National Rodeo held each year at the San Francisco Cow Palace. Every year, Novato Horsemen members ride from Novato to the Halleck Creek Riding Club in Nicasio and sponsor a BBQ, which benefits its handicapped members. Novato Horsemen also collect food and toys for those in need during the holidays.
