State Highway 285 (SH 285) is a state highway that runs from Riviera in southern Texas, near Corpus Christi, west to Hebbronville.

Beginning at a junction with US 77 (Future I-69E) at Riviera in Kleberg County, SH 285 runs southwest and west to a junction with US 281 (Future I-69C) at Falfurrias in Brooks County.

In Riviera the highway is known as Olive Avenue; in Falfurrias it is known as Rice Street.

[2] On September 26, 1939 as part of a general redescription of the state highway system, SH 285 was extended east to its current end, replacing a part of SH 16.

Most of the terrain covered by SH 285 is lightly populated ranch and oil country.
