Expedition 61 was the 61st Expedition to the International Space Station, which began on 3 October 2019 with the undocking of the Soyuz MS-12 spacecraft. The Expedition was commanded by ESA astronaut Luca Parmitano, who became the third European and first Italian astronaut to command the ISS. Parmitano, along with his Soyuz MS-13 colleagues Aleksandr Skvortsov and Andrew Morgan, and Christina Koch from Soyuz MS-12, transferred over from Expedition 60. They were joined by Oleg Skripochka and Jessica Meir, who launched on 25 September 2019 on board Soyuz MS-15.

According to a Flight Planning Integration Panel (FPIP) document obtained by NASAspaceflight.com in June 2019, Expedition 61 was tentatively scheduled to see two visits from Commercial Crew Development spacecraft. However, schedule slippages meant these visits will not occur.
Four spacewalks were conducted to repair the Alpha Magnetic Spectrometer. The repairs were conducted by ESA astronaut Luca Parmitano and NASA astronaut Andrew Morgan. Both of them were assisted by NASA astronauts Christina Koch and Jessica Meir who operated the Canadarm2 robotic arm from inside the Station. The spacewalks were described as the "most challenging since Hubble repairs".
