- Named for Harold Lee Alden (January 10, 1890 – February 3, 1964), an American astronomer. The majority of Alden's work consisted of measurements of stellar parallaxes, proper motions and visual observations of long-period variable stars. He was best remembered for his published studies in long-focus photographic astrometry from both McCormick and Yale Observatories.
- Alden was among the long list of farside names approved by the IAU in 1970 and published in Menzel, 1971.
- In the planning for Apollo 8, the first manned circumlunar mission (1968), this crater (which did not then have an official name) was referred to informally as "See" (source: Phil Stooke's LPOD).
