Rodrigo Álvaro Tello Valenzuela (born 14 October 1979 in Santiago) is a Chilean footballer currently playing with Turkish club Beşiktaş JK.

Left-footed, he usually operates as a left midfielder, but can also appear in the middle. He's also known for his long-distance shots.

Tello began his career at Universidad de Chile making his professional debut in 1999. He quickly made a good impression, being named the best midfielder the country in 2000, and was transferred to Sporting Clube de Portugal for a fee of €7 millions in January of the following year, at the same time as compatriot Mario Cáceres; it was a then club record for the Portuguese first division side.

After a slow start, Tello eventually became an important first-team member - although he would be used mainly as a substitute - and even saw some time at left defender.

In the 2007 summer, Tello moved to Turkey and signed with Beşiktaş JK. In his second season, he was named to the Team of the Season, as his club won the double.
