William Curtis Shelly (September 17, 1878 – August 13, 1951) was a businessman and political figure in British Columbia.

He represented Vancouver City from 1928 to 1933 in the Legislative Assembly of British Columbia as a Conservative.

He was also president of the Home Oil Co. Ltd., Canada Grain Export Co. Ltd., Guaranty Savings and Loan, Crescent Beach Development Co. Ltd., Grouse Mountain Highway and Scenic Resort Ltd. and the Shelly Building.

Shelly projected an increase of government revenues and a small surplus for the following fiscal year; instead, revenues decreased and expenditures were larger than projected, resulting in a then-record deficit of $4.8 million.

He suffered a large personal financial loss when share prices for Home Oil Co. Ltd. bottomed out in the years following the stock market crash.
