The Healdsburg Prune Packers are the collegiate level summer baseball team which has been playing at Recreation Park since 1921. Operating under various organizational structures over the years, the Packers became a part of the California Collegiate League in 2014. As of 2024, they became a charter team of the newly-formed Pacific Empire League.

In February 1921, under the leadership of the Healdsburg Chamber of Commerce, a new baseball team was organized. The first game was played on 15 May 1921 with Red Corrick pitching. The first year included 21 Sunday games against the Nucoa Butters, the Petaluma Leghorns, the Santa Rosa Rosebuds, the San Francisco Ninantic Parlor, the Vallejo Y.M.I., Oakland Maxwell Hardware, San Francisco M.J. B. Coffee Kids and the San Francisco Associated Terminals.

In the first five years, the Prune Packers earned an enviable record: 1921 14 W, 9 L; 1922 20 W, 6 L; 1923 22 W, 4 L; 1924 20 W, 6 L; 1925 7 W, 2L. In July 1925, the team was suddenly disbanded by the Healdsburg Chamber of Commerce and the baseball committee when the finances of the team proved untenable. At the time of the disbanding, the Santa Rosa and Petaluma teams had already folded and the St. Helena and Napa teams were expected to disband shortly.

In 1930, the Prune Packers represented Healdsburg in the Sonoma County League.

While the 1931 season was threatened with cancellation because of lack of local support, the Prune Packers won the championship in the Redwood Empire League.

In 1932, the Prune Packers attempted to operate as a non-league-affiliated team to play various local teams. Only one game appears to have been played, against Lakeport, which the Packers lost.

A full 1933 season of 20 games was played, but the final game was canceled because of the approaching starts of colleges and high schools. The Prune Packers won 12 games and lost 8.

In 1938, the I.O.O.F. sponsored Healdsburg baseball using the organization's three links as a logo and without using the Prune Packers name.
