"Thank you to everybody, and my fans who have come out," said Loggins, 59, just before putting his hands in wet cement at the sidewalk gallery outside the Guitar Center on Sunset Boulevard.
The Grammy-winning singer-songwriter started his musical career as a folksinger in the `60s, later playing in such rock bands as the Electric Prunes.
After being hired as a songwriter for a Los Angeles music publisher, he joined forces with singer-producer Jim Messina, leading to three platinum and five gold albums and such singles as "Danny's Song."
The team split up in 1976, and Loggins struck platinum as a soloist.
Known for his soulful voice and lyrics, he won a Grammy in 1980 for writing the Doobie Brothers hit "What a Fool Believes" with Michael McDonald, and in 1981 for "This Is It."
Loggins also composed songs for movie soundtracks including "Top Gun" and "Footloose."
His new album "How About Now" came out in February.
The RockWalk was established in 1985 to honor musicians who have made a significant contribution to the history of music.
