A search for antiproton decay has been made at the Fermilab Antiproton Accumulator. Limits are placed on 13 antiproton decay modes. The results include the first explicit experimental limits on the muonic decay modes of the antiproton, and the first limits on the decay modes ℯ-γγ and ℯ-ω. The most stringent limit is for the decay mode→ ℯ-γ. At 90% C.L. we find that τ¯ / B (→ ℯ-γ)>7x105 yr. The most stringent limit for decay modes with a muon in the final state is for the decay → μ-γ . At 90% C.L. we find that τ¯ / B (→ μ -γ) >.5x104 yr.
