Jajinci (Serbian Cyrillic: Јајинци, pronounced [jâjiːntsi]) is an urban neighborhood located in the municipality of Voždovac, in Belgrade, Serbia.

It was the site of the worst carnage in Serbia during World War II when German occupational forces executed nearly 80,000 people, many of them prisoners of the nearby Banjica concentration camp.

Jewish women and children from German Sajmište concentration camp, killed in a special gas truck on their way to Belgrade were also buried here.

Once a small village far from downtown Belgrade, Jajinci today has grown into one continuous metropolitan area with the rest of the city.

Unlike neighboring Banjica, it was never developed with high modern buildings and remained a settlement of smaller, family houses, but did evolve from agricultural into a typical suburban area with most inhabitants working in Belgrade.

Victims were mostly gathered and sent to the execution by the occupational Nazi forces in Serbia, but also by the Independent State of Croatia authorities and the Serbian Quisling regime.

[18] A large memorial park, with a monument to the victims, was opened on 20 October 1964, marking the 20th anniversary of the Partisan army entering Belgrade.

Architect Bogdan Bogdanović, head of the commission, noted that such work can't be done in concrete, as suggested by the author, so instead a sculpture of stainless steel was made.

The government remained silent until November 2022 when videos and photos of quads revving engines and speeding over the burial ground surfaced.
