Silver Lake is an unincorporated settlement in Saint Mary's Township in Perry County, Missouri, United States.

The change was doubtless suggested by postal authorities, who prefer single names, but custom triumphed over law and the two words are used.

[3] The town of Silver Lake was laid out by Simon DuVall (1782-1865)[4] on land that was granted to him in 1856.

The parish first started as a log cabin mission church served by the Vincentians from Perryville, Missouri in the 1855.

In the early 1870s, Father Joseph Hellwing, who had just become pastor of St. Mary's at Biehle, Missouri, also gave services here.
