The year 1877 in science and technology involved some significant events, listed below.
- June 19 – Eadweard Muybridge successfully produces a fast-motion sequence of photographs showing a horse in movement, Sallie Gardner at a Gallop, using multiple cameras at Palo Alto, California, demonstrating that a running horse has all four legs lifted off the ground at once. The sequence could be run on a Zoopraxiscope.
- August 12 – American astronomer Asaph Hall discovers Deimos, the smaller of the two moons of Mars. On August 18, he discovers the larger, Phobos.
