Walter Avarelli (3 June 1912 – 1987) was an Italian bridge player, a member of the famous Blue Team, with whom he won nine Bermuda Bowls and three World Team Olympiads from 1956 to 1972.

Avarelli was born in Rome and became a judge there. He first took up rudimentary bridge during World War II when more than thirty years old.{{cite book |last = Mollo |first = Victor |author-link = Victor Mollo |title = The Bridge Immortals |publisher = Hart Publishing Company, Inc. |location = New York |pages = 19–21 |year = 1968 }} Along with interests in tennis, riding and motor racing, he was especially noted for "his addiction to gastronomy".

Avarelli was the longtime partner of Giorgio Belladonna using the Roman Club bidding system. They improved the system together and presented it in a book that was published in at least two Italian editions, 1958 and 1969.
