The Shell Houston Open is a regular golf tournament on the PGA Tour. It is currently played in April at Redstone Golf Club in the Houston suburb of Humble. Shell and the Houston Golf Association are the main sponsors of the tournament. The 2008 purse was $5,600,000, with $1,008,000 going to the winner.

The event was played at several Houston venues until the 1970s, starting at River Oaks Country Club in 1946 before moving to Memorial Park Golf Course in 1947 and, after a year off, moving again to Pine Forest Country Club in 1949 and BraeBurn Country Club in 1950. After this period of wandering about, the event settled in at Memorial Park from 1951-1963. In 1964 and again in 1965, the event was played at Sharpstown Country Club, before moving to Champions Golf Club from 1966-71 and Westwood Country Club in 1972.

In 1973 the event ventured outside of Houston, being played at Quail Valley Country Club in Missouri City, Texas. In 1975, the event relocated to The Woodlands, Texas, first at Woodlands Country Club until 1984, and subsequently at the TPC at The Woodlands until 2002. In 2003, the event moved to its current location at Redstone Golf Club.
