The Hackers on Planet Earth (HOPE) conference series is a hacker convention sponsored by the security hacker magazine 2600: The Hacker Quarterly that until 2020 was typically held at Hotel Pennsylvania, in Manhattan, New York City.

Usually occurring biennially in the summer, there have been fourteen conferences to date. HOPE 2020, originally planned to be held at St. John's University, was instead held as a nine-day virtual event from July 25 to August 2, 2020. The most recent conference, "HOPE XV", was held at St. John's University in Queens from July 12 to 14, 2024. HOPE features talks, workshops, demonstrations, tours, and movie screenings.

HOPE was significantly inspired by the quadrennial Hack-Tic events in the Netherlands which also inspired the annual Chaos Communication Congress (C3) held in Germany. Summercon was an additional influential predecessor.
