Charles Wilson Adam (31 October 1848 – 3 September 1924) was a Scottish engineer who served as the first president of Spanish club Recreativo de Huelva from 1889 to 1896.

[2][5] The local press describes "Don Carlos" as a true English gentleman, respectful, and very fond of the habits of life in Huelva.

[6] In either 1883 or 1884, Adam, now a manager of the local gasworks, met Mackay, who approached him to ask for permission to organize football and cricket matches on a plot of land that had been given to Adam's gasworks by the city council, located at the end of Vega Larga, opposite to the Gas Factory, right in front of the current La Merced bullring.

[6] Under his presidency, Adam signed, among others, the plans to close the Gasworks grounds in 1888, and then turned it into a playing field, the so-called Campo del Velódromo in June 1892, a sports venue that he promoted and designed as a member of the club's board, together with Mackay, and which was inaugurated by Recreativo on 20 August of that year, suitable for the practice of football and cricket.

[4] From 1890 onwards, he began organizing on an annual basis, the celebration of the so-called Juegos Olímpicos (Olympic Games) in Huelva, six years before they were officially established by Pierre de Coubertain.

[4] Although his daughter Maria married in the British Consulate in Seville,[4] both she and her sister Isabel eventually returned to Great Britain, while the other, Flora, died in Tasmania.

[4] He thus died in Loughborough, England, on 3 September 1924, at the age of 75, but the news did not reach Huelva until a few days later, on 8 September, and his great friend Macka was so affected by this news that he left the club's presidency just two days later, after nearly three decades at the helm of the club, being replaced by a Huelva native, the former player José Ochoa de Mora.
