The French freighter La Coubre () exploded in the harbour of Havana, Cuba, on 4 March 1960 while it was unloading 76 tons of grenades and munitions. Seventy-five to 100 people were killed, and many were injured. Fidel Castro alleged it was an act of sabotage on the part of the United States, which denied any involvement. Events La Coubre, a 4,310-ton French vessel, was on 4 March 1960 unloading her cargo of 76 tons of Belgian munitions she had transported from the port of Antwerp in Belgium to Havana. Unloading explosive ordnance directly onto the dock in Havana was against port regulations. Ships with such cargoes were supposed to be moored in the center of the harbor and their high-risk cargo unloaded onto lighters. The ship exploded at 3:10 pm. Thirty minutes after the first explosion, while hundreds of people were involved in a rescue operation organized by the Cuban military, a second, more powerful explosion resulted in additional fatalities and injuries.

The death toll was between 75 and 100; more than 200 people were injured.

On 7 March, the Miami Herald reported charges made by Jack Lee Evans, an American who had just returned from Havana where he had been working for and living with William Alexander Morgan, an American who had commanded rebel forces during the Cuban Revolution. He said he had boarded the La Coubre on 2 March with Morgan and others to transport machine guns and ammunition to the NIAR.
