An election to Preseli Pembrokeshire District Council was held in May 1987. It was preceded by the 1983 election and followed by the 1991 election. On the same day there were elections to the other district local authorities and community councils in Wales.
There was a slight reduction in the number of seats. Those abolished included Nevern, Steynton, and one of the three seats in both Fishguard and Milford North and West. Other wards were realigned or renamed.
Stan Hudson stood as a Conservative, having not been affiliated to any party at the 1983 election.
Labour had held one of the three seats in 1983 but it had been subsequently lost at a by-election. Basil Woodruff, the sitting county councillor, won a seat at the expense of another Independent.
The number of seats was reduced from three to two.
