Jackson Park, Urban park in Alameda, California, United States

Chochenyo Park, long known as Jackson Park, is a small tree-lined municipal park on Park Avenue in Alameda, California, one block from the Park Street business district. Its centerpiece is a 100-foot-wide, 1,200-foot-long oval green, with benches and a bandstand but no play structures, fields or courts.

The park began in 1867 as the oval centerpiece of the Alameda Park Tract, a 100-foot-wide, 1,200-foot-long strip laid out for wealthy residents. The city gained title to the land in 1894 after years of condemning absentee owners' properties, and the park was established in 1895. Named Alameda Park, it was renamed Jackson Park in 1909 for President Andrew Jackson, then became Chochenyo Park in January 2021.

The park's name Chochenyo comes from the language of the Ohlone, the original inhabitants of Alameda island. The Clark Memorial Bench at one end carries the plaque "In Memory of My Dumb Friends," a 1920 gift from Isabelle Clark to honor her husband; residents replaced it in the early 2000s. Local lore links the bench to singer Jim Morrison, who spent time in Alameda.

The park lies on Park Avenue, one block from the Park Street business district and south of Encinal Avenue. It is a passive park with no play structures, fields or courts, so visitors come for benches and walking under the trees. The Clark Memorial Bench sits at one end, and the 1890 bandstand by Joseph A. Leonard stands in the grounds.

At one end of the park stands a large concrete bench with a plaque reading "In Memory of My Dumb Friends." Many locals link it to singer Jim Morrison, who lived in Alameda, but Isabelle Clark gave it in 1920 in honor of her husband; residents replaced it in the early 2000s.
