Moveable Feast is a nonprofit organization based in Baltimore, Maryland which provides food and services to individuals suffering from HIV/AIDS, breast cancer, and those afflicted with terminal illness. Its founder Baltimore City Health Department official Robert Mehl recognized a need in the community for such services during the epidemic of HIV/AIDS in the United States. He assembled a committee at the direction of then-Baltimore mayor Kurt Schmoke, and the organization was founded in 1990. In its first year the organization's staff of three provided food and services to 60 clients biweekly and twice per day. By 2001 this had increased to attending to the nutrition needs of about 550 people in the region.

In Christianity, a moveable feast or movable feast is an observance in a liturgical calendar that occurs on different dates (relative to the dominant civil or solar calendar) in different years. The most important set of moveable feasts are a fixed number of days before or after Easter Sunday, which varies by over 40 days since it depends partly on the phase of the moon. In Eastern Christianity, these moveable feasts form what is called the Paschal cycle.
