Joshua Hopkins Marvil (September 3, 1825 – April 8, 1895) was an American merchant and politician from Laurel, in Sussex County, Delaware.

With the growth of the peach orchards, he started the Marvil Package Company, a basket and crate manufacturing business in Laurel.

Nevertheless, he was popular, and after refusing his party's nomination for governor in 1882 and 1890, he finally agreed in 1894, in spite of his advanced age and poor physical condition.

For a generation bitter memories of Republican actions during the Civil War had kept the Democrats firmly in control of the government throughout Delaware.

However, during this period gas executive J. Edward Addicks, a Philadelphia millionaire, established residence in Delaware, and began pouring money into the Republican Party, especially in Kent and Sussex County.
