La Capital is a local daily newspaper published in Mar del Plata, Argentina, established in 1905.

Tettamanti was a former steward at landowner Miguel Martinez de Hoz's ranch or estancia at Chapadmalal, then a rural area southwest of Mar del Plata.

The paper was instrumental to the election as Mar del Plata's mayor of Jose Heguilor, another member of the committee, in 1906.

The municipality faced a series of crisis from 1906 to 1911, a period characterized by the collapse of locally-elected governments and direct rule by commissioners appointed by the province of Buenos Aires senate.

In this new context, La Capital eventually gave support to the Junta de Resistencia ("Board of Resistance"), a political space that pressed for the continuity of locally-chosen authorities.
