Las Toninas is a town in La Costa Partido of the Province of Buenos Aires, Argentina.

The shore had been the site of a shipwreck in 1883 of a commercial vessel registered in the British Empire, whose captain settled nearby and established the Estancia Los Ingleses.

[1] The shore at Las Toninas is distinguishable from its sister communities' by the extensive growth of tamarix bushes.

[2] Las Toninas is also known as the "Fiber Optical Capital" in Argentina;[citation needed] because it is the single point where submarine optical fiber networks reach Argentina via several landing cable stations, by companies such as Level 3 (with its SAC ring), TIWS (Atlantis 2), Telecom-Antel (Bicentenario cable system), and Telefónica (SAM 1).
