{{Main|Interstate 10 in Arizona}}
In [[Arizona]], the highway is designated the Pearl Harbor Memorial Highway. The portion through [[Phoenix, Arizona|Phoenix]] is named the [[Papago Freeway]], and it is a vital piece of the [[Roads and freeways in metropolitan Phoenix|metropolitan Phoenix freeway system]]. This designation starts at [[Arizona State Route 101|State Route&nbsp;101]] (SR&nbsp;101; Loop&nbsp;101), near 99th Avenue, and continues eastward to the interchange southeast of downtown, which is the terminus of [[Interstate 17|I-17]].

Near [[Buckeye, Arizona|Buckeye]], the freeway has milemarkers posted every {{convert|0.2|mi|km}} from 112.2 to 110.8 with the [[Interstate shield]] and direction of travel posted on the westbound lanes. On the eastbound lanes, milemarkers from 110.8 to 112.2 do not include the I‑10 shield and direction of travel.

From the southern terminus of I-17 to the southernmost junction with [[Arizona State Route 202|SR&nbsp;202]] (Loop&nbsp;202), the highway is signed as the Maricopa Freeway. This name holds true as well for I-17 from its southern terminus to the Durango Curve south of Buckeye Road. From Loop&nbsp;202 south to the eastern terminus of [[Interstate 8|I-8]] just southeast of [[Casa Grande, Arizona|Casa Grande]], the highway is declared the Pearl Harbor Memorial Highway. The [[Arizona Department of Transportation]] also has maps that show it as the Maricopa Freeway, while the [[American Automobile Association]] and other sources show it as the Pima Freeway. The latter's name is used on a stretch of Loop&nbsp;101 from Loop&nbsp;202 to I-17.

Between I-17 in Phoenix and the [[Interstate 19|I-19]] interchanges in [[Tucson, Arizona|Tucson]], I-10 is included in the federally designated [[CANAMEX Corridor]], extending from [[Mexico City, Mexico]], to [[Edmonton, Alberta]].

In Tucson, between I-10 mileposts&nbsp;259 and 260 are interchange ramps connecting I-10 with the northern terminus of I-19.

The highest elevation along I-10 occurs just east of Tucson, {{convert|20|mi|km}} west of [[Willcox, Arizona|Willcox]], at the milemarker&nbsp;320 exit for the rest stop. The westbound lanes of I-10 briefly cross above {{convert|5000|ft|m}} above [[sea level]].
