Mikel Aranburu Eizagirre (born 18 February 1979) is a Spanish retired professional footballer who played as a midfielder.

[1][2] Born in Azpeitia, Gipuzkoa, Aranburu made his professional debut aged 18, in the last round of 1996–97 against CD Logroñés, courtesy of manager Javier Irureta.

From his fourth season onwards he became a full member of the main squad, being essential as the Basques finished second in La Liga in 2002–03 by contributing 34 games and two goals.

[3] He continued to be an important first-team member during the Segunda División campaigns, appearing in 35 matches in 2009–10 to help the Txuriurdin to return to the top flight after three years.

He equalled a career-best five goals,[3] including two in a 4–0 away win over Getafe CF – he only played five minutes in the match[5]– and the all-important last-minute winner at home against Real Zaragoza in the 36th round (2–1),[6] as the side narrowly retained their league status.
