The Smith Estate, also known as El Mio (Spanish: "mine" or "my place"), is a historic Victorian house perched on a hilltop in the Highland Park section of Los Angeles, California.

It has been the residence of a judge who wrote books on occultism, the head of the Los Angeles Railway, and a deputy mayor; and as a shooting location for the cult films Spider Baby, Silent Scream and Insidious: Chapter 2.

"[4] Hatch became a judge in 1880 and gained fame presiding over the Perkins-Baldwin case—a breach of marriage promise case against Lucky Baldwin, a gold prospector who became one of the wealthiest men in Los Angeles and founded Santa Anita Park on his estate.

[22] In 1900, Henry Huntington named Smith, described as "an old-time employe (sic) of the Southern Pacific, having been with the road in its early days," as the superintendent of the Los Angeles Railway's streetcar lines.

Smith house which pointed an architectural finger from its hill top, a beacon for lost souls who traveled out that far ... A few other dwellings there were, but these were the landmarks.

The Times noted that the house, built on a hilltop with four bedrooms and maids' quarters, had a view of Gage's office at Los Angeles City Hall.

In 1964, Jack Hill shot the horror comedy cult film Spider Baby (also known as Attack of the Liver Eaters)[34] at the Smith Estate.

Insidious: Chapter 2 was shot extensively at El Mio, and the home is featured - inside and out - as one of the film's major locations.
