738 Alagasta (/æləˈɡæstə/) is a main belt asteroid. It was discovered from Heidelberg on 7 January 1913 by German astronomer Franz Kaiser. The asteroid was named in honor of Gau-Algesheim, previously Alaghastesheim, which is the home city of the discoverer's family. This body is orbiting at a distance of 3.04 AU with a period of 5.29 years and an eccentricity of 0.055. The orbital plane is inclined at an angle of 3.53° to the plane of the ecliptic.

Photometric measurements made of the asteroid during 2015 produced a light curve that showed a rotation period of 18.86±0.01 h with a brightness variation of 0.11 in magnitude. The asteroid is roughly 63 km in diameter and has a low albedo.
